Abstract

EVALUATION OF ANTIHYPERGLYCEMIC ACTIVITY AND PHYTOCHEMICAL SCREENING USING LEAVES OF GYMNEMA SYLVESTRE

Rahila Khatoon*, Kuldeep Singh and Manoj Kumar Mishra

ABSTRACT

The aim of this study was to investigate the Evaluation of antihyperglycemic activity and phytochemical screening using leaves of Gymnema sylvestre in alloxan (ALX) induced diabetic rats. Diabetes was confirmed after 5 days of single intraperitoneal injection of ALX (150 mg/kg) in albino Wister rats. Aqueous and ethanol extracts of leaves of Gymnema sylvestre (200 and 400 mg/kg) and Glibenclamide (10 mg/kg, p.o.) orally administered daily for 15 days, blood was withdrawn for glucose determination on 0, 1, 10 and 15 days respectively. Five days before the termination of the experiment, the oral glucose tolerance test (OGTT) was performed to assess the glucose tolerance. For this purpose, overnight fasted rats were fed glucose (2 g/kg) orally and blood was collected at 0, 30, 60 and 120 min interval from orbital sinus for glucose estimation. On the15th day, overnight fasted rats were sacrificed and blood was collected for the determination of high density lipoproteins cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), total cholesterol (TC), total glycerides (TG) and total proteins (TP). Aqueous and ethanol extracts of leaves of Gymnema sylvestre at doses of 200 and 400 mg/kg showed significant reduction is blood glucose, lipid when compared to diabetic control group. We concluded that aqueous and ethanol extracts of leaves of Gymnema sylvestre possess Antidiabetic. The histopathology study of pancreas was also performed which showed hypoglycemic effect.
