ABSTRACT Linn. (Kachnar) (- Leguminosae) is popular ornamental , commonly known as Cow’s paw. Bauhinia variegata is a widely used as medicinal plant distributed in the tropical regions. According to WHO third world countries depends mainly native medicinal plants for their health purpose. various part i.e. , buds, stem, roots, bark, , have been used since ancient times for the treatment of a wide range of diseases. It is used traditionally in dysentery, diarrhea, hemorrhoids, piles, edema, laxative, anti-helmintic, astringent, anti-leprotic, wound healing, anti-goitrogenic, anti-tumor, antidote for snake poisoning, dyspepsia and carminative disease. It have numerous chemical values and is rich phytochemicals such as flavonoids, tannin, kaempferol, terpenoids, saponins, reducing sugars steroids, cardiac glycosides and quercetin. Studies on the medicinal and biological importance of B. Address for variegata have been reported. In modern studies and scientific Correspondence knowledge on the biological/ medicinal properties is demonstrate that B. variegata used as a anti-bacterial, anti-helmintic, anti-arthritic, Malacology anti-inflammatory, anti-diabetic, immunomodulatory, hepato- Laboratory, Department of protective, anti-oxidant, trypsin inhibitor and anti-carcinogenic Zoology, DDU activity.

B. variegata plant could be utilized as an alternative source of antimicrobial Anti-tumour / Cytotoxic activity drugs. Methanolic, chloroform and aqueous Rajkapoor et al. 36 and Gupta et al. 76 extracts of B. variegata fractions shows anti- noted anti-tumour activity of ethanolic bacterial activity against both gram positive extract B. variegata against dalton‘s ascetic and gram negative bacteria namely- Bacillus lymphoma (DAL) on Swiss albino mice. cereus, Staphyllococcus aureus, Klebsiella Ethanolic extract of stem bark of B. pneumonia, Escherichia coli, and variegata shows the chemoprevention and Pseudomonas pseudoalcaligenes33. Anti- cytotoxic effect against N- bacterial activity in methanol extract is more nitrosodiethylamine induced liver tumour in potent than aqueous extract32.The alcoholic rats and human cancer cell lines at a dose of extract of leaves of B. variegata showed 200 mg/kg44. Oral administration of maximum antimicrobial activity compared ethanolic extract of B. variegata effectively with other organic solvent extracts13. The suppressed liver tumour induced by N- methanol extract from both in vivo and in nitrosodiethylamine induced elevated level vitro generated plants of B. variegata were of serum glutamate pyruvate transminase tested against a number of microbes, only (SGPT), serum glutamate oxaloacetate Escherichia coli and Pseudomonas transminase (SGOT), alkaline phosphatase aeruginosa were found to be resistant at a (ALP), total bilirubin, gama glutamate concentration of 50 μg/ml2.

Pandey Anti-arthritic and Agarwal44 observed anticarcinogenic Rajkapoor et al.78 investigated the and antimutagenic potential of B. variegata anti-arthritic activity of ethanolic extract of methanolic extract on Swiss albino mice B. variegata by the oral administration of using a skin carcinogenesis and melanoma ethanolic extract at the tested dose level of tumour model, along with micronucleus and 250 mg/kg on complete Freund’s adjuvant chromosomal aberration tests. He found that (CFA) induced arthritis in rat for 15 days. At the significant prevention of skin papilloma the end of 15 days, the rats were sacrificed, model, with delayed appearance and their blood was collected and then serum reduction in the cumulative number of was separated. After that various parameters papillomas in the DMBA + B. variegata + such as alanine amino transferase (ALT), croton oil treated group as compared to the alkaline phosphatase (ALP), total DMBA + Croton Oil group. C57 Bl mice cholesterol and triglycerides were estimated. which received a 50% methanolic extract of In the level of various antioxidant enzymes B. variegata extract at the doses of 500 and were also evaluated in liver and kidney of 1,000 mg/ kg body weight for 30 days normal, arthritic control and extract treated showed increase in life span and reduced the rats such as catalase, glutathione peroxidase tumour size significantly44. Pandey and (GPx), superoxide dismutase (SOD) and Agarwal, 44 noted in antimutagenicity lipid peroxidase (LPO). The result of these studies, a single application of B. variegata studies shows that administration of this extract at doses of 300, 600 and 900 mg/kg significantly Paw Edema volume in rat and dry weight, 24 hours prior the administration altered the biochemical parameters and also of cyclophosphamide (at 50 mg/kg) level of various antioxidant enzymes which significantly prevented micronucleus got affected in arthritic rats. From this study, formation and chromosomal aberrations in it was concluded that the ethanolic extracts bone marrow cells of mice, in a dose of this plant showed significant antiarthritic dependent manner. Tewari et al.77 effect in rats47. investigated the traditional use of B. variegata against anti tumour activity. The Anti-Obesity anti tumour potential of B. variegata was Balamurugan and Muralidharan79 studied by 3-(4,5 dimethyl thiozole-2-yl)- investigated the anti-obesity effect of 2.5- diphenyl trtrazodium bromide (MTT) methanolic extracts of stem and root bark of and sulpherhodamine B (SRB) the two B. variegata by oral administration of cancer cell line (Hep-2, HeLa) and one methanolic extracts at the tested dose level normal cell line (BRL3A). The result of of 200 and 400 mg/kg in female rats fed MTT and SRB showed seven extract of with hyper caloric diet for 40 days. At the cytotoxic to the cancer cell line and less end of 40 days, various parameters was toxic towards normal cell lines. The evaluated such as body weight (BW), feed preliminary Phytochemical screened out intake, high density lipoproteins (HDLP), flavonoids asantitumour activity.

This was acuminata and Indoplanorbis exustus. These attributed to the presence of β-sitosterol in snails are the intermediate host of liver fluke the stem and tendency to release the Fasciola hepatica and Fasciola gigantica, serotonin level in the brain. Thus this which causes 94% fascioliasis in the finding showed a significant anti-obesity buffalo’s population of Eastern Uttar activity79. Pradesh in India82 & 83. The active molluscicidal component of Bauhinia Pesticidal Properties: variegata leaf is soluble in organic solvent such as acetone, carbon tetra chloride, Anti-helmintic activity chloroform, ether and ethanol. The toxicity Aqueous and Chloroform extract of of ethanolic extract of Bauhinia variegata bark of B. variegata were investigated for leaf powder is higher than other organic their anti-helmintic activity against solvents. Singh et al. 28 characterized that Pheretima posthuma and Ascardia galli. All quercetin is the active component present in extracts exhibited a dose dependent (25, 50 Bauhinia variegata leaf by column and 100 mg/ml) inhibition of spontaneous chromatography and thin layer motility (paralysis) and time of death of the chromatography. Toxicity of 96h exposure worms35. Extract obtained from bark not period of column purified fraction of B. only killed the Pheretima posthuma but also variegata leaf (LC50 -5.98 mg/l) against L. killed the Ascardia galli. The observations acuminata is lower than the values of were comparable with standard drug synthetic molluscicides- carbaryl (14.40 piperazine citrate at a concentration of 20 mg/l) 84, phorate (15.0 mg/l) 84, formothion mg/ml and distilled water as control.
