Evaluation of Anti–Inflammatory, Anti–diabetic activity of Indian Bauhinia vahlii (stembark)

Abstract

ObjectiveTo evaluate the anti–inflammatory and antidiabetic property of Bauhinia vahlii (stem bark) with preliminary phytochemical profile of the extracts. MethodsThe dried whole plant material (1 400 g) was packed in soxhlet apparatus and extracted successively with Pet. Ether (PE) to defat the drug, petroleum ether was removed from the powdered defatted drug which was then extracted with benzene (BE), chloroform(CE) and 95% of Ethanol (EE) as increasing polarity and all extracts screened for anti–inflammatory and antidiabetic activity using carrageenan induced paw edema and streptozotacin induced diabetic respectively. The toxicity and phytochemical screening were done using standard procedure. ResultThe preliminary phytochemical tests revealed the presence of alkaloids, flavonoids, phytosterol, phenolic compounds, and glycoside. While carbohydrates, protein, gums and amino acids were absent. The acute toxicity study of various extracts of Bauhinia vahlii was conducted and dose of 353 mg/kg is fixed for anti–inflammatory and antidiabetic perperty. The pet ether, chloroform and ethanolic extract of Bauhinia vahlii significantly decreased the paw edema induced by carrageenin in rats at a dose of 353 mg/kg comparable to standard ibuprofen (100 mg/kg). Similarly in case of antidiabetic property, the ethanolic and chloroform extract of Bauhinia vahlii at a dose level 353 mg/kg, showed significant reduction in blood sugar level from 2 to 24 h in progressive manner comparable to standard glibenclamide (5mg/kg).
