Preamble
Arthritis and rheumatism form a complex array of disorders. There are significant sources of
suffering and disability, and their prevalence and impact are increasing all around the globe as
people are living longer lives. Humoral medicines and its numerous cross cultural variant offers
an important prespective on the conceptualization and treatment of arthritis. The present work
provides a descriptive account of use of Catpusphadhya churna in rheumatic disorders. The
discussion explores the pharmacognostical , chemical quantification of active markers and
pharmacological evaluation of Catpusphadhya churna. This work provides a framework for its
use in arthritis.
The drugs used in Catpusphadhya churna are physiologically beneficial and non toxic medicines.
These drugs individually has been shown to have antioxidant, anti-inflammatory and antiarthritic
activity.
The ayurvedic properties of these drugs suggests the potencial therapeutic use of these in
inflammatory and autoimmune disease. So, Catpusphadhya churna will be examined for these
activities.

Working Hypothesis
Chapter 2
Working Hypothesis
The Ayurveda suggests that the arthritis is caused primarily by an excess of ama and lack of
agni. This can be caused by poor digestion and weakened colon, resulting in the accumulation of
undigested food and the build up of the waste matter. Poor digestion allows the toxins to
accumulate in the body and problems with the colon allows the toxin to reach the joins.
Ayurvedic approach to treat arthritis includes :
 Strengthening the metabolic pathways that prevent the blockage of circulatory channels
to joints, by impurities.
 Strengthening of digestion to create nutritional plasma that is pure and easy to assimilate.
 Improving the lubrication of joints.
 Anything that aggravate or overly activaes vata, will increase the sensitivity and
experience of pain in body.
According to this line of treatment for arthritis ayurveda suggest the use of drugs which can
stimulate the digestive fire (agni), reduce the ama, stabilize vata and reduce the arthritic pain.
 Black pepper stabilizes vata and stimulates agni.
 Vidang increases digestive fire.
 Dill seeds stabilzes vata and kapha.
The hypothetical model shown above depicts that Catpusphadhya churna may work as an antiinflammatory and antiarthritic agent, by this way decrease the complications of rheumatoid
arthritis.

Aim of Present Work

Aim Of Present Work
Standardization can create trust and confidence in the products and increase market relevance. It
is an essential requirement for the open exchange of information; without it, the network will
simply not work. The Practitioner as well as the Consumer now seek assurance from the
manufacturer about quality, safety and efficacy of a readymade Herbal Supplement or
Medication.An average person's diet, lifestyle and other social habits, all which play important
roles in disease and treatment, are completely different today. Hence the earlier
recommendations for herbs for specific disease states may not hold true today unless validated in
today's times.Phenotypic changes in plant species. Hence the original pharmacological claims of
these medicinal plant species need to be revalidated. Pharmaceutical research is aimed at
meeting the medical needs of the population for whom appropriate therapeutic remedies are not
available or at those that are available are unsafe for prophylactic use for various disorders.
While meeting medical needs, research also has to ensure that market needs for such
exist.Rheumatoid arthritis is an autoimmune disease for which no sure allopathic treatment is
available.
The present study is mainly aimed to
Standardize “Catpusphadhya Churna” in terms of identity, purity, content of assay.
Chemical quantifiation of active markers present in the formulation.
Perform pharmacological activity of catpusphadhya churna.

Introduction
4.1 Introduction to disease
Rheumatoid arthritis (RA) is a form of arthritis that causes pain, swelling, stiffness and loss of
function in your joints. It can affect any joint but is common in the wrist and fingers. More
women than men get rheumatoid arthritis. It often starts between ages 25 and 55. You might
have the disease for only a short time, or symptoms might come and go. The severe form can last
a life time.
Rheumatoid arthritis - the second most common form of arthritis - affects other parts of the body
besides the joints. Osteoarthritis is the most common type of arthritis. Rheumatoid arthritis is
different from osteoarthritis, the common arthritis that mostly affects cartilage and often comes
with older age. RA can affect body parts besides joints, such as your eyes, mouth and lungs. RA
is an autoimmune disease, which means the arthritis results from your immune system attacking
your body's own tissues.

Introduction
In some patients with rheumatoid arthritis, chronic inflammation leads to the destruction of the
cartilage, bone, and ligaments, causing deformity of the joints. Damage to the joints can occur
early in the disease and be progressive. Moreover, studies have shown that the progressive
damage to the joints does not necessarily correlate with the degree of pain, stiffness, or swelling
present in the joints.
Rheumatoid arthritis (RA) is an autoimmune disease that causes chronic inflammation of the
joints. Rheumatoid arthritis can also cause inflammation of the tissue around the joints, as well
as in other organs in the body. Autoimmune diseases are illnesses that occur when the body's
tissues are mistakenly attacked by their own immune system. The immune system is a complex
organization of cells and antibodies designed normally to "seek and destroy" invaders of the
body, particularly infections. Patients with autoimmune diseases have antibodies in their blood
that target their own body tissues, where they can be associated with inflammation. Because it
can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic
illness and is sometimes called rheumatoid disease. However, rheumatoid arthritis is typically a
progressive illness that has the potential to cause joint destruction and functional disability.
No one knows what causes rheumatoid arthritis. Genes, environment and hormones might
contribute. Treatments include medicine, lifestyle changes and surgery. These can slow or stop
joint damage and reduce pain and swelling.

Introduction
Treatment of Rheumatoid Arthritis
There's no cure for RA, although progression of the disease can be slowed, the symptoms can be
treated, and a person can be helped to adjust to the condition. Treatments include:

Physiotherapy – heat, cold and exercises to relieve pain and stiffness, improve joint
movements and strengthen muscles.

Rest – when there is a worsening of the joint inflammation.

Occupational therapy – including training, advice, counselling and provision of splints,
and aids such as walking aids and specialised cooking utensils – these can help people do
daily activities more easily and with less pain.

Drugs. These (often taken in combinations) play an important part in dampening the
inflammatory and autoimmune process.
The earlier drug therapy begins, the better the outcome. Drug treatments include:

Mild painkillers like paracetamol and aspirin.

NSAIDs (non-steroidal anti-inflammatory drugs) . These dampen the inflammation,
but they can have side effects: chiefly gastric ulcer and bleeding from the stomach and
duodenum. They're effective in reducing the pain and the swelling though, and in milder
cases, may be enough to control the condition. They seem to work well in some people
but not so well in others. They include older NSAIDs such as indomethacin, sulindac,
ibuprofen, diclofenac and naproxen; and newer NSAIDs called the COX 2 inhibitors
such as rofecoxib and celecoxib. The COX 2 inhibitors are said to produce less gastric
bleeding, but have been shown to increase the risk of heart disease – in 2004, rofecoxib
(trade name Vioxx) was withdrawn from the market. Recent evidence suggests that there
may be an increased risk of heart disease with the NSAIDs as well.


Introduction
Corticosteroids may be used in more severe cases. They suppress the immune response,
and are used either continuously as tablets or capsules, or as injections directly in the
affected joint in a flare-up.

Disease-modifying anti-rheumatic drugs (DMARDs) . These don't cure the condition
either, but can slow its progress, though they can be associated with serious side effects –
so people on these drugs need to be carefully monitored. They include: antimalarial drugs
like hydroxychloroquine; penicillamine; immunosuppressant drugs like azathioprine and
methotrexate; sulphasalazine; leflunomide; and intramuscular gold injections. Another
class of drugs acts by blocking tumour necrosis factor (and are very effective but very
expensive). These include infliximab, etanercept and adalimumab. Another drug
sometimes used is anakinra, which blocks interleukin-1.
In some cases, surgery (for example a knee replacement) is an option, where a joint has been
badly damaged.
Because of the side effects associated with the allopathic treatment as mentioned above, now the
demand for herbal treatment for this disease is now increasing which ensures safety.

Introduction
4.2 Herbals and Ayurveda
The ayurvedic system of medicine is prevalent in India, since the vedic period and as earlt as the
dawn of human civilization.these medicine are of plant, animal or mineral origin or mixture of
them. There are well laid down procedures to make these preparation and as a result of which it
is claimed that their bioavailability is enhance.
Though ayurveda has undergone a number of changes in the course of its history, it still remains
the mainstay of medical relief to a large section of population of nation. The World Health
Organization (WHO) estimates that about 80 % of the population living in the developing
countries rely almost exclusively on traditional medicine for their primary health care
needs.there has been a tremendous increase in the usage of traditional and herbal medicines in
the past few years, not only among modern consumers of herbal products.
India has been a traditionally rich source of various types of medicinal plants. Traditional
medicines are and will be the indomitable area of pharmacognosy. Currently, plant based drugs
are researched, dispensed, formulated and manufactured in modern framework rather than in
form of galenical preparation or conventional dosage forms.hence pharmacognosy has become
an interface among various branches of pharmaceutical sciences. It is now emerging as
interdisciplinary science that incorporate inputs from chemistry, pharmacology, pharmaceutical
technology and biotechnology directed towards natural products based drug discovery.
Because of the various side effects associated with the current therapies for rheumatoid arthritis
and as the reason for its occurrence is not clear as per medical research, no drug therapy
effectively works on it. So there is need to switch to ayurvedic treatment for its cure.

4.3 Churna
4.3.1 Introduction
Churnas are preparations comprising of fine powders of drugs and may be simple or compound.
Simple churna comprises of only one ingredient while a compound one consists of more than
one ingredient. The principle of using churna is due to the fact that therapeutic value of most of
the substances greatly increases when they are reduced to very fine state of subdivision.
4.3.2 Method of preparation
Drugs are cleaned and dried properly. Drugs are kept separately and powdered. They are sieved
and each one of them powdered and weighed separately, and then mixed together. It is then kept
in air tight containers in cool and dry place.
4.3.3 Characteristics and preservation
The powder is fine of atleast 80-mesh sieve. It should not adhere together or become moist. The
finer the powder, the beter irs therapeutic value. They retain potency for one year and should be
kept in airtight containers.

Introduction
4.5.4 Rock salt
Halite is the mineral form of sodium chloride , NaCl, commonly known as rock salt. Mineral solid homogeneous inorganic substances occurring in nature having a definite chemical
composition. Rock salt - naturally occurring crystalline sodium chloride (halite). Na, atomic
number 11, sodium - a silvery soft waxy metallic element of the alkali metal group; occurs
abundantly in natural compounds (especially in salt water); burns with a yellow flame and reacts
violently in water; occurs in sea water and in the mineral halite (rock salt).
Halite forms isomeric crystals. The mineral is typically colorless or white, but may also be light
blue, dark blue, purple, pink, red, orange, yellow or gray depending on the amount and type of
impurities. It commonly occurs with other evaporate deposit minerals such as several of the
sulphates, halides and borates. The primary difference between rock salt and ordinary table salt
is the size. Rock salt forms in very large, chunky crystals, as opposed to the small crystals seen
in table salt. Like table salt, rock salt also has an assortment of trace minerals which can have an
impact on how it behaves chemically. Because of the large crystal size, rock salt is not usually
used directly in cooking, since it takes a long time to dissolve.
Rock salt, purified by nature, is considered superior to table salt, due to its richness in natural
minerals and lack of chemicals and additive. Many micro organisms cannot live in an overly
salty environment: water is drawn out of their cells by osmosis. For this reason salt is used to
preserve some foods, such as smoked bacon or fish. It can also be used to detach leeches that
have attached themselves to feed. It is also used to disinfect wounds. It Improve Digestion.
Rock Salt as the name says is obtained from Salt mines in its pure natural form. It is very low in
sodium content as compared to the common salt. In Ayurveda, Rock Salt is recommended in
place of Sea Salt or common salt which is termed as a non-vegetarian salt as it has many
impurities like animal and human excreta's, dead animal flesh etc. Rock Salt is also an effective

Introduction
medicine for various problems related to the digestive system and those due to worms.
Benefit from the purity of rock salt.
One of the benefits of rock salt is what it lacks, which is chemicals and additives. Regular table
salt goes through a harsh refining process in which the salt from the mine is crushed, refined and
packaged. This removes the natural minerals found in rock salt, including iodine, which has to
be added back in the manufacturing process of table salt.
From ancient times to today, it is believed that salt that comes naturally from mines benefit the
digestive system in many ways. When taken with food, salt derived from pure rock improves
appetite, improves digestion, decreases gas, and promotes proper bowel function. It is used as a
spice and an ingredient in ice cream. It Alleviate respiratory symptoms. It is said that the salt
cleans mucus from the airways and decreases the severity of inflammation in the sinuses. After
the discovery of the first natural rock salt cave in Britain, scores of people attest to cures of
many respiratory symptoms ranging from the common cold to asthma and allergies. It Increase
your intake of dietary minerals. It is common knowledge that our diets should be rich in
minerals, which aid in
body metabolism, water balance, and bone health. Rock salt is rich in
minerals. In addition to sodium chloride (salt), such as calcium, magnesium, copper and iron. In
addition, over 50 trace minerals are found in rock salt.
Moreover, there are no side effects of consuming Rock Salt. It is also an effective remedy for
teeth and Gum problems as an external food constituent. Scientists do not advise use of common
salt because of the logical reason that Sea water which contains so much of harmful wastes
cannot be purified however one tries to purify it. Therefore, according to scientists, common salt
may be harmful to us as compared to the controlled use of Rock Salt. The chemical composition
also of both the salts are different for (e.g.), the Rock Salt has a low sodium content, is a
Naturally refined salt, and has a natural anti-caking property whereas, common salt has a
comparatively high sodium content, is a chemically refined salt and toxic anti-caking chemicals
like potassium/sodium ferro-cyanide are added for common salt to achieve the anti-caking
property. Rock salt in one's diet is beneficial specially for people having heart ailments and
therefore advised to reduce the salt intake.

Review Of Literature
For piperine :
1. Indian Herbal Pharmacopoeia1 described the analytical method for the determination of
Piperine by HPTLC.
2. In official methods of Analysis of AOAC International2 stated that piperine in solution
isomerizes when exposed to light.
3. Indian Council of Medical Research of India3 described the HPTLC method for analysis
of piperine.
4. M. K . Santosh et.al.4 discussed that Piper longum Linn. and Piper nigrum Linn. are used as
spices and medicines. Quantitative determination of piperine was undertaken to provide an
easy and simple analytical method, which can be used as a routine quality control method.
RP-HPLC was performed using methanol and water as mobile phase. The detection and
quantification was performed at a wavelength of 345 nm. Linearity of detector response for
piperine was between the concentrations 0.005% to 0.1%. The correlation coefficient
obtained for the linearity was 0.998. The assay value of piperine for fruit and root of P.
longum was found to be 0.879% and 0.31%. The assay value of piperine for fruit of P.
nigrum was 4.5%. The recovery value of standard piperine was 99.4%. Low value of
standard deviation and coefficient of variation are indicative of high precision of the method.
5. Kedar Kumar Rout et.al.5 developed a simple, sensitive, and rapid high-performance thin
layer chromatographic (HPTLC) method has been established for estimation of piperine in
commercial Ayurvedic formulations and in the fruits of Piper nigrum Linn, and Piper
longum Linn. Chromatography was performed on aluminum foil HPTLC plates coated with
0.2 mm layers of silica gel F 254 , with hexane-acetone 6.5: 3.5 ( v/v ) as mobile phase. The

development distance was 76 mm, the temperature 25 ± 5°C, and the chamber was saturated
for 5 min. Piperine was quantified at 340 nm, its wavelength of maximum absorbance. Under
the conditions used the R F of piperine was 0.33 and the limit of detection (LOD) was 4 ng
per zone. The calibration plot was linear in the range of 10 to 60 ng per zone with a
correlation coefficient of 0.9996. Recovery was in the range 98.76 to 100.70%. This HPTLC
method was found to be reproducible, accurate, and precise and could be used to detect
piperine at nanogram levels. The method is a very simple and cost-effective means of
quantitative estimation of piperine in Ayurvedic formulations.
6. S.K Chauhane et.al.6 developed HPLC method to determine pipeine in different Piper
species. This method can be used for detection, monitoring and quantification of piperine.
7. A Kumar et. al.7 studied the antiinflammatory activity of the Piper longum dried fruit's oil
in rats using the carrageenan-induced right hind paw edema method. The activity was
compared with that of standard drug ibuprofen. The dried fruit's oil inhibited carrageenaninduced rat paw edema. The results indicated that the dried fruit's oil produced significant
(p< 0.001) antiinflammatory activity when compared with the standard and untreated
control.
8. S.C. Jagdale et.al.8 worked on Myocardial ischemia, a serious cardiac problem which
should be diagnosed and treated effectively to prevent its complications. Many plant based
medicine have been utilized for the effective treatment in cardiac problems. Myocardial
ischemia was induced in rats by administration of isoproterenol. Petroleum ether extract of
root and piperine from roots of Piper longum Linn. were subjected for evaluation of their
anti-oxidant activity by DPPH scavenging method. Lipid peroxide and Glutathione values in
myocardial ischemic rats have also been estimated by inducing myocardial ischemia by
using isoproterenol. It has been found that at 50 mg mL-1 concentration pet ether extract and
piperine exerts 74.12 and 72.13% of inhibition. Pet ether extract and piperine pretreatment
decreases lipid peroxide level and maintain glutathione content to near normal in treated rats.
The present study shows that the extract of the root of the plant and piperine exert antioxidant activity and are protective in the myocardial ischemic condition.

9. Dipak Kulkarni et. al.9 provided easy and simple analytical HPTLC method for
determination of piperine from Piper nigrum.
10. Samudram P et.al.10 studied the combined hepatoprotective effect of Bi- herbal ethanolic
extract (BHEE)
against carbon tetra chloride (CCl4) induced hepatic damage in rats.
Ethanolic extract from the leaves of Eclipta alba and seeds of Piper longum at a dose level
of 50 mg/kg body weight was administered orally daily once for 14 days. The substantially
elevated serum marker enzymes such as SGOT, SGPT, ALP, LDH, ACP,
GT and 5’
Nucleotidase, due to CCl4 treatment were restored towards normalization. The biochemical
parameters like total protein, total bilirubin, total cholesterol, triglycerides, and urea were
also restored towards normal levels. In addition, BHEE significantly decreased the liver
weight of CCl4 intoxicated rats. Silymarin at a dose level of 50 mg/kg was used as a standard
reference also exhibited significant hepatoprotective activity against CCl4 induced
hepatotoxicity. The results of this study strongly indicate that BHEE has got a potent
hepatoprotective action against CCl4 induced hepatic damage in rats.
11. A. B. Wood et.al.11 developed a reversed-phase high-performance liquid chromatographic
(HPLC) method for the selective determination of piperine, in pepper or its oleoresins, is
described and evaluated. It employs a fully-capped, bonded C18 stationary phase (ODS-2)
and an acetonitrile - aqueous acetic acid mobile phase, with ultraviolet (UV) detection.
Piperine is extracted from ground pepper by refluxing 3h with ethanol (96% v/v), whilst
homogenized oleoresins are simply dissolved in the same solvent. At all stages, light must as
far as possible be excluded from the solutions, so as to minimize the photoisomerization of
piperine. Quantitation, based on peak areas, is achieved by reference to purified piperine as
external standard. Results obtained for a range of samples at four different detection
wavelengths showed virtual wavelength-independence, indicating a good degree of peak
purity. All samples were also analysed by the ISO spectrophotometric method (ISO 5564,
1982), which invariably yielded higher results because of the contributions from other
pepper alkaloids (e.g. piperyline and piperettine) to the UV absorption. Since some of these
other alkaloids are believed to contribute to the pungency of pepper, the HPLC method is
proposed as complementary to the spectrophotometric method, rather than as a replacement
for it. The HPLC method gave results with relative standard deviations less than ±3% for

longum and mixture thereof by their fingerprinting pattern.
13. Koul Surrinder et. al.13 studied that piperine inhibits both constitutive and inducible
cytochrome P450(CYP) dependent drug metabolizing enzyme.
14. Koul I.B et. al.14 evaluated antihepatotoxic potencial of piperine in order to validate its use
in traditional therapeutic formulations. This plant principle exerted a significant protection
against tert butyl hydroperoxide and CCl4 hepatotoxicity by reducing both invitro and invivo
lipid peroxidation, enzymatic leakage of GPT and AP and by preventing the depletion of
GSH and total thiols in the intoxicated mice. Silymarin, a known hepatoprotective drug was
tested simultaneously for comparision. Piperine showed a lower hepatoprotective potencial
than silymarin.
15. Sharma G et. al.15 reported piperine as therapeutic agent and bioavailability enhancer.
16. Mujumdar A.M et. al.16 used different acute and chronic experimental models and reported
that piperine acted significantly on early acute changes in inflammatory processes and
chronic granulative changes. I also acted partially through stimulation of pituitary adrenal
axis. Exudaive changes in both acute and chronic models, however were insignificant.
17. Gupta S.K et. al.17 Stated that piperine is an inhibitor of various hepatic and other enzymes
involved in the biotransformation of drugs. Preliminary pharmacokinetic suggested the
increased bioavailability of nimesulide co administered with piperine. Results for the present
study suggest a better therapeutic index for the nimesulide-piperine combination indicating
that this combination would further reduce the frequency of adverse effects associated with
nimesulide alone.

19. İlhami Gülçin19 investigated water and ethanol crude extracts from black pepper (Piper
nigrum) for their antioxidant and radical scavenging activities in six different assay, namely,
total antioxidant activity, reducing power, 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) free
radical scavenging, superoxide anion radical scavenging, hydrogen peroxide scavenging, and
metal chelating activities. Both water extract (WEBP) and ethanol extract (EEBP) of black
pepper exhibited strong total antioxidant activity. The 75 µg/ml concentration of WEBP and
EEBP showed 95.5% and 93.3% inhibition on peroxidation of linoleic acid emulsion,
respectively. On the other hand, at the same concentration, standard antioxidants such as
butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and α-tocopherol
exhibited 92.1%, 95.0%, and 70.4% inhibition on peroxidation of linoleic acid emulsion,
respectively. Also, total phenolic content in both WEBP and EEBP were determined as gallic
acid equivalents. The total phenolics content of water and ethanol extracts were determined
by the Folin-Ciocalteu procedure and 54.3 and 42.8 µg gallic acid equivalent of phenols was
detected in 1 mg WEBP and EEBP.
20. D Hooge R et. al.20 showed that piperine significantly block convulsions induced by
intracerebroventricular injection of threshold doses of kainite, but to have no or slight effects
on convulsions induced by L- glutamate, N-methyl D aspartate or guanidine succinate

of the different fractions PEPN increased in a concentration dependent manner. R3 and R2
fraction of PEPN in 500Pg/ml inhibited the peroxidation of a linoleic acid emulsion by
60.48±3.33% and 58.89±2.51%, respectively. In DPPH free radical scavenging assay, the
activity of R3 and R2 was found almost similar. R3 (100Pg/ml) fraction of PEPN inhibited

2. Sarin J.P.S. and Ray G.k.25 “ The Indian Journal of Pharmacy”,1961,23(12),330-31 studied
a simple colorimetric method for the estimation of embeline in Embelia ibes. The method is
based on color reaction between embeline and aniline, the color intensity of which is directly
proportional to the concentration of embeline.
3. Bheemasankara

and vilangin in Embelia ribes.
4. Zutshi U, Johri R.K, Atal C.K27, ”Indian Journal of Experimental Biol.”,1989,27(7),656
showed that potassium embelate was established as a centrally acting analgesic in mice and
rats. Mixed µ and k receptor binding sites in the brain may be involved in the analgesic
activity. Analgesic activity was compared wih morphine, although it was not antagonized by
naloxone, indicating a central site of action differed from opiates.
5. Choudhary R.P, Ibrahim A, Bharati H.N28, “Electronic Journal of Food and Plt Chem”
2007, 2(1),20 showed that emeline in fruit of myrisana Africana was quantified using HPLC
and HPTLC. U.V detection was used in both analytical methods to examine the presence of
quantity of embeline. The assay provided a good accuracy and reproducibility for the
quantitative analysis of embeline.
6. Chauhan S.K, Singh B.P, Agrawal S29, “Indian Drugs”1999,36(1),41 showed a simple and

embelines was found to be more active than either haloembeline or embeline itself. P- amino
benzoate derivative of embeline was also synthesized and studied for biological activity.
8. Patel R.K, Pundarikakshadu K., Patel M.M31, “Indian Journal of Pharmaceutical
Sciences”, 2006, 227 developed a tablet formulation of embeline employing the wet
granulation and direct compression techniques. This study was also carried out to design a
suitable dissolution medium for embeline. Effects of different diluents like lactose,
microcrystalline cellulose, and co-crystallized lactose- microcrystalline cellulose were studied
for improving the flow and compressibility. Binders such as starch paste and alcoholic
polyvinyl pyrrolidine were used to optimize the crushing strength of the formulation.
Solubility study of embeline in different media revealed that embeline has optimum solubility
in phosphate buffer pH 8 and in 2% aq. SLS solution. Incorporation of 10% v/v ethanol in
phosphate buffer of ph 7.4, significantly increased the solubility of embeline. These solutions
were also found to be the most suitable media for dissolution of embeline in dissolution
studies.
9. Chitra M, Sukumar E, suja V, Devi C.S32, “ Journal of Chemoherapy”, 1994,109-13
studied embeline, plant based benzoquinone derivative and this found to exhibit significant
antitumor activity in methyl cholanthrene induced fibrosarcoma in albino rats besides
enhancing their survival time. The drug also has an appreciable action on pain and
inflammation. The changes in DNA, RNA and protein levels in various organs in the tumors
bearing control and the drug treated animals were also studied.
10. Guru L.V, Misra D.N33, “Journal Res. Indian Med”,1996,1,47 studied anthelmentic
activity for aqueous and alcoholic extract of vidang on children infested with ascarides and
found that alcoholic extract cured 80% of cases, whilst the aqueous extract cured 55%,
expelling the worms and rendering the stool free from ova.

11. Chander H, Ahemed S.D34, “J. of Stored Prod. Res.’,1989,25(2),87 studied embeline as
insecticidal. The efficiency as insecticidal against Tribolium castaneum and other insect was
established in wheat sample by embeline at 0.18 % brought about mortality even after 8
months of storage. The reproduction of insect was also reduced significantly.

13. M.Chiitra et . al.36, Indian Journal of Pharmacology 2003; 35: 241-244 investigated the
effect of a naturally occurring antitumour compound embelin on its lipid lowering activity
in experimental fibrosarcoma. Methylcholantherene induced fibrosarcoma was transplanted
in rats. After 30 days, embelin (50 and 100 mg/kg, p.o.) was administered as suspension for
a period of 20 days. The blood sample was collected on 21st day and the liver and the
kidney were also removed for studying the lipid profile in serum and the tissues. The levels
of total cholesterol, phospholipids, triglycerides and free fatty acids were markedly elevated
in the serum of tumour bearing rats. Significant alterations were also observed in the lipid
profile of liver and kidney. These changes were significantly reversed in embelin (100
mg/kg) treated animals. The reversal of altered lipid to normal values by embelin in rats
with experimentally induced tumour further supports the antitumour potential of embelin.
14. R. Paul Choudhury et.al.37 ,quantified Embelin in fruits of Myrsine africana L.
(Myrsinaceae)
using high performance liquid chromatography (HPLC) and high
performance thin layer chromatography (HPTLC) at 288 nm and 333 nm respectively. UV
detection was used in both analytical methods to examine the presence and quantity of
embelin. The assays provided a good accuracy and reproducibility for the quantitative
analysis of embelin. The results obtained in both analytical methods did not show any
significant overall difference (P = 0.66 ) although a trend to slightly lower range could be
found for the HPTLC method. Embelin content in Myrsine africana was similar to that
found in Embelia ribes Burm. f. and therefore has potential use as a substitute and an
alternative source of embelin

6.1 Pharmacognostic And Physicochemical Investigation Of Raw Materials
6.1.1 Introduction
Plant based medicines have been used by mankind since time immemorial. According to the
report of Whorld Health Organization(WHO), over 80 % of world population relies on
traditional system of medicine, largely plant based, to meet their primary health care. The
effectiveness of these system, in turn, mainly depends upon the proper use and sustained
availability of genuine raw material. Global resurgence of the interest in herbal drugs has led to
the need of their mass production which perhaps was not even contemplated by the traditional
medicine practitioners who prepared and dispensed the medicine on a personal and individual
bias.
Large scale production of medicinal plant products nesseciate the availability of standards to
ensure their quality, efficacy and safety. These are mainly concerned with the quality of raw
material and methodology adopted during the procurement, handling and processing them. The
prime importance is given to standardization of raw materials which are used in such
formulation to ascertain the efficacy and safety. Many guidelines are published especially by
WHO, IHP, API, Ayurvedic formulary, ICMR, AOAC and many others for the standardization
and evaluation of these materials.
Hence in the present investigation the attempt was made to standardize the materials under the
study for the pharmacognostic, physicochemical and phytochemical parameters according to the
guidelines.

Procured samples were powdered and used for standardization. Powder passed through 40 mesh
sieve. Standardization of these powdered samples was carried out for the usual pharmacognostic,
physicochemical and chromatographic parameters as described below.
6.1.2.2 Methodology
6.1.2.2.1 Foreign matter analysis
Here drug sample are sieved and then with the help of magnifying lens checked for the presence
of impurities. Then impurities and fines are considered as foreign matter and weighed and %
foreign matter calculated.
6.1.2.2.2 Microscopic examination method
The coarse seed powder was boiled with chloral hydrate for 5 minutes, then stained with
phloroglucinol and HCL (1:1) and observed for the microscopic features under low power (10x)
and high power (40 x).

6.1.2.2.3 Loss on drying
To estimate loss on drying, 5 gm of air dried powdered plant material were accurately weighed
in a dried and tarred flat weighing bottle. The sample was dried to constant mass in a hot air
oven at temperature 105 ºC. The loss on drying was determined with respect to air dried plant
material.
6.1.2.2.4 Determination of ash value
a.) Total ash : 3g of accurately weighed powdered drug was taken in a tarred silica crucible and
incinerated at a temperature not exceeding 4500C until free from carbon and constant weight,
cooled and weighed .
b.) Acid-insoluble ash : Total ash obtained was boiled for five minutes with 25 ml of
dilute
Hydrochloric acid. The insoluble matter was collected on an ash less filter paper, washed with
hot water and ignited, cooled and weighed. The percentage of acid insoluble ash was calculated
with reference to powder.
c.) Water-soluble ash : Total ash obtained was boiled for five minutes with 25ml of distilled
water, cooled and collect the insoluble matter on an ash-less filter paper, washed with hot water
and ignited for 15 minutes at temperature not exceeding 4500C. The percentage of water-soluble
ash was calculated with reference to powder.

6.1.2.2.5 Determination of extractive value
The extractive value of drug helps to determine the amount of soluble constituents
in a
given amount of medicinal plant material, when extracted with solvents. The extraction of any
crude drug with a particular solvent yields a solution containing different phytoconstituents. The
composition of these phytoconstituents in a solvent depends upon the nature of drug and solvent
used.
a.) Alcohol soluble extractive value: 5g seed powder of A, subulatum was macerated
with
100ml of ethanol in a closed flask, shaking frequently during the first 6hrs and allowed to stand
for 18hrs. Thereafter it was filtered rapidly taking precaution against loss of ethanol. Evaporate
25ml of filtrate to dryness in a tared flat bottom shallow dish dried at 1050C and weighed.
Percentage ethanol soluble extractive was calculated with reference to the dried powder.
b.) Water soluble extractive value: Above procedure was repeated using water in place of
alcohol.
6.1.2.2.6 Phytochemical investigation:
All drugs were rxtracted in methanol and extract was concentrated. These extracts
were then subjected to various qualitative tests for identification of various plant constituents
like alkaloid, glycoside, volatile oil, flavaoids , tannins etc.
Qualitative chemical tests for identifying various phytoconstituents present were carried out on
various extracts of A. subulatum Roxb fruit constituents as follows.
 Tests for Glycosides :
Test I: Extract 200 mg of powder drug by warming in a test tube with 5 ml of dilute (10%)
sulphuric acid on a water bath at 100oC for two minutes, centrifuge or filter, pipette out
supernatant or filtrate. Neutralize the acid extract with 5% solution of Sodium hydroxide
(note the volume of NaOH added). Add 0.1 ml of Fehling’s solution A and B until

Chapter 6
Experimental Work
alkaline (test with pH paper) and heat on a water bath for 2 minutes. Note the quantity of
red precipitate formed and compare with that formed in Test II.
Test II: Extract 200 mg of the drug using 5 ml of and boil on water bath. After boiling add equal
volume of water to the volume of NaoH used in the above test. Add 0.1 ml of Fehling’s
A and B until alkaline (red litmus changes to blue) and heat on water bath for two
minutes. Note the quantity of the red precipitate formed.
Compare the precipitates of Test II with Test I. If the precipitate in Test-II is greater than
in Test-I, then Glycoside may be present. Since Test I represent the amount of free
reducing sugar already present in the crude drug, whereas Test-II represents the
Glycoside after acid hydrolysis.
 Tests for Alkaloids :
a. Mayer’s test (Potassium mercuric iodide solution): To extract/sample solution, add few
drops of Mayer’s reagent, creamy white precipitate is produced
b. Dragendroff’s test (Potassium bismuth iodide solution): To extract/sample solution, add
few drops of Dragendroff’s reagent, reddish brown precipitate is produced.
c.
Wagner’s test (Solution of Iodine in Potassium Iodide): To extract/sample solution,
add few drops of Wagner’s reagent, reddish brown precipitate is produced.
d.
Hager’s Test (Saturated solution of Picric acid): To extract/sample solution, add few
drops of Hager’s reagent, yellow precipitate is produced.
e.
Tannic acid test: To extract/sample solution, add few drops of Tannic acid solution,
buff precipitate is produced.
 Tests for Phenolic Compounds :

of an ,  unsaturated –  lactone in the aglycone.
6.1.2.2.7 Determination of volatile oil content from dill fruit powder of various
mesh size
Volatile oil is isolated or determined by using clavenger apparatus. In order to
determine the
volume of oil, the powder material is distilled with water and the distillate is collected in a
graduated tube. The aqueous portion separates automatically and is returned to the distillation
flask. Since the volatile oil possesses the mass density lighter than water, it floats on the top of
the aqueous phase.
Apparatus/Method:
Clavanger apparatus was used to isolate volatile oil. Here drug powder ws mixed with water and
heated at constant temperature.Volatile oil was lighter than water, so it started floting on water
layer. After few hours when oil ceased to isolate, the process was stoped and after measuring
volume oil was removed and stored carefully.
6.1.2.2.8 Estimation of carvone in volatile oil by titrimetry
Weigh accurately 1.5 gram of dill oil (specific gravity- 0.916 gm/ml) in conical flask. Add 10 ml
of hydroxyl amine hydrochloride reagent prepared in 90 % ethanol. Place the tightly closed flask
in water bath for heatingt at 80 °C neutralize the liberated acid with 1N potassium hydroxide

prepare in ethanol until the red color changes to yellow. Continue heating and titrate again until
yellow color remains persistent. The reaction will acquire 30-40 miniutes for completion.The
indicator for notice of change in color is already added in preparation of hydroxylamine
hydrochloride reagent. Here after addition of reagent, the red color produced is titrated with
KOH to yellow color and then heated. This is repeated till persistent yellow color is obtained.
Calculate content of carvone by following factor:
Each ml of 1 N KOH ~ 0.1514 g of carvone.
6.2 Simultaneous estimation of piperine in Piper nigrum, embeline in Embelia
ribes, carvone in Anethum sowa.
6.2.1 Introduction
Herbal medicine has been enjoying renaissance among the customers throughoutthe world.
However one of the impediments in the acceptance of the Ayurvedicformulation is the lack of
standard quality control profiles (Bagul and Rajani, 2005). The quality of herbal medicine, that
is, the profile of the constituents in the final products has implication in efficacy and safety. Due
to the complex nature and inherent variability of the chemical constituents of the plant based
drugs, it is difficult to establish quality control parameters and modern analytical techniques.are
expected to help in circumventing this problem.
Standardization and analysis of chemical markers of ayurvedic and other polyherbal formulation
is always difficult. Quantitative estimation of chemical markers of each ingredient in the
polyherbal formulation requires ideal separation technique by which these markers are separated
with highest purity and with least interference from each other. For botanicals and herbal
preparation, there is a requirement of scientific proof. HPTLC is the most commonly applied for
the analysis of multiple constituents present in the medicinal plants and herbal preparation.
In the present study we report the development of a HPTLC method for the
simultaneous
estimation of piperine, carvone and embeline in black pepper, dill seeds and vidang respectively.

Experimental Work
Precision
Precision was determined by repeatability, intra day and inter day (Table 3) reproducibility
experiment of the proposed method. Repeatability was evaluated for degree of repeatability of
spotting by preparing and analyzing the standard solution of the drug three times. The intra day
reproducibility was determined by analyzing freshly prepared solution in triplicate at three
different concentration whereas inter day reproducibility was checked by analyzing the standard
solutions at three different days under same operative condition.
Limit of Detection and Limit of Quantification
Limit of Detection of Piperine, Embeline and Carvone were found o be 0.2 mcg,0.05 mcg and
0.2 nl and Limit of Quantification were found to be 0.5mcg, 0.1mcg and 0.5 nl respectively.
Specificity
Specificity of an analytical method is its ability to measure the analyte accurately and spefically
in the presence of component that may be expected to be present in the sample matrix. Test and
standard of Piperine, embeline and carvone were spotted on the TLC plate, developed and
scanned as described above and it was observed that other constituents present in the formulation
did not interfere with the peak of the markers. Therefore the method was specific. The test
chromatogram (Figure 14) was compared with the standard (Figure 12) and were found to be
similar.
6.3 Standardization Of Catpusphadhya Churna
6.3.1 Introduction
According to the report of World Health Organization (WHO), over 80 per cent of the world
population relies on the traditional systems of medicine, largely plant based, to meet their
primary health care. Efficacy and safety of the herbal drugs and formulations including
ayurvedic and other traditional formulations are always under a big question mark. Furthermore,
limited availability of medicinal plants of consistent quality has been perhaps one of the toughest
impediments for reliable biological, pharmacological, chemical and clinical evaluation besides
their use in health care. Lack or inadequacy of quality standards has been a discouraging factor
M.Pharm (Pharmacognosy)

6.3.2.3 Standardization of catpusphadhya churna
6.3.2.3.1 Loss on drying
To estimate the loss on drying, 5 gm of the air dried Churna is accurately weighed in a dried and
tared flat weighing bottle. The sample was dried to constant mass in a hot air oven at
temperature 105o C. The loss on drying was determined with respect to air-dried plant material.
6.3.2.3.2 Determination of ash value
a.) Total ash
4 g of the air-dried Vasavaleha was taken and accurately weighed, in a previously ignite and
tared crucible (silica). The material was placed in an even layer and ignited by gradually
increasing the heat to 500-600o C until it appeared completely white, indicating the absence of
carbon. The material called ash was cooled in desiccators for 30 min and then weighed. The
content of total ash was determined with respect to air-dried material.
b.) Acid insoluble ash water soluble ash
To the crucible containing the total ash, 25 ml of HCL (~70g/l) was added, covered with a watch
glass and boiled gently for 5 minutes. The watch glass was rinsed with 5 ml of hot water and
washing was added to the crucible. Insoluble matter was collected on an ash less filter paper and
washing of this filter paper was carried out with hot water until the filtrate was remaining
neutral. The filter paper containing the insoluble matter was transferred to the original crucible,
which is then dried on a hot plate and ignited to constant weight. Allowed the residue to cool in a
suitable desiccator for 30 minutes, and then weighed without delay. The content of acidinsoluble ash was calculated with respect to the weight of air dried material.
c.) Water-Soluble Ash Value
To the crucible containing total ash, 25 ml of water was added and boiled for 5 minutes.
Insoluble matter was collected on an ash less filter paper. The residue was washed with hot
water and ignited in a crucible for 15 minutes at a temperature not exceeding 450o C. The
weight of the residue was subtracted from the weight of total ash. The content of water soluble
ash was determined with respect to the weight of the air dried material.

Accurately weighed 10 gm of Vasavaleha was taken in glass-stopper conical flask. The
content was macerated with 100 ml of distilled water for 6 hours with frequent shaking
and then allowed to stand for 18 hours. The content was filtered taking care not to lose
any solvent. 25 ml of filtrate was transferred to a tarred flat-bottomed dish and evaporated to
dryness on a water-bath and dried at 105o C for 6 hours, cooled in desiccators for 30 min and
weighed without delay. Percent water soluble extractive value was calculated with respect to the
original weight of the air-dried material.
b.) Ethanol soluble extractive
Accurately weighed 10 gm of Vasavaleha was taken in glass-stopper conical flask. The content
was macerated with 100 ml of methanol for 6 hours with frequent shaking and then allowed to
stand for 18 hours. The content was filtered taking care not to lose any solvent. 25 ml of filtrate
was transferred to a tarred flat-bottomed dish and evaporated to dryness on a water-bath and
dried at 105o C for 6 hours, cooled in desiccators for 30 min and weighed without delay. Percent
alcohol soluble extractive value was calculated with
respect to the original weight of the air-dried material.

Summary Of Work
Standardization of formulation is required to have assurance about biological activity and
clinical consistency. Efforts are made here to standardize Catpusphadhya churna in terms of
various pharmacognostic, physicochemical and phytochemical parameters to establish reliable
values for respective and correlate with further work on instrumental analytical methods like
HPTLC.
Following conclusion have been drawn from the detailed study carried out under the aim of
“Standardization of atpusphadhya churna”
The raw materials for the formulation were procured from different location. It is concluded
from the pharmacognostical, physicochemical and phytochemical studies that all the raw
materials are genuine.
The proposed HPTLC methods for simultaneous estimation of piperine, embeline and carvone
seems to be accurate, precise, reproducible and repeatable. It is for the first time, when different
samples of this formulation and its raw materials are estimated and compared for the respective
active constituents.
The pharmacognostic, physicochemical and phytochemical parameters can now be laid down for
this formulation
This formulation showed very good antioxidant and anti-inflammatory activity, so an attempt
must be made to extend the investigations for the pharmacological study like
immunomodulatory and antiarthritic study.
