Abstract

The present work was aimed to evaluate the antidiabetic effect of 50% hydroethanolic extract of Aristalochia bracteolata Lam. leaves on 36 adult male albino Wistar rats weighing about 190-220 gms. Rats were divided into 6 groups of 6 rats in each. Group-I served as normal control while diabetes was induced in Group-II, III, IV, V and VI using Streptozotocin at a dose of 55 mg/kg bw by intraperitonial injection. After induction of diabetes Gtoup – II served as diabetic control. Group – VI rats were treated with 600 μg/kg bw/day of standard drug (Glibenclamide) while Group – III, IV and V rats were orally administred with 50% hydroethanolic leaf extract of Aristalochia bracteolata Lam. at the doses of 150, 300 and 450 mg/kg bw/day respectively for 28 days. To determine hypoglycemic effect of 50% hydroethanolic leaf extract of A. bracteolata Lam., blood and tissue biochemical parameters were assayed in normal, diabetic control and treated groups. Oral administration of 50% hydroethanolic extract of A. bracteolata Lam. leaves for 28 days exhibited a significant (p
