Abstract:
Our aim was to evaluate the antihyperglycemic and antilipid peroxidative effect of ethanolic extract of Pongamia pinnata (Linn.) Pierre (Leguminosae) flowers (PpEt) in normal rats and alloxan induced diabetic rats. Hyperglycemia, elevated lipid peroxidation [thiobarbituric acid reactive substances (TBARS)] and disturbed nonenzymatic [Vitamin E, Vitamin C and glutathione] and enzymatic antioxidants status were noticed in alloxan induced diabetic rats. The oral administration of ethanolic extract of Pongamia pinnata flowers (300 mg/kg bw) showed significant antihyperglycemic, and antilipidperoxidative effects and enhancement in antioxidants defense system in alloxan induced diabetic rats. However, no significant characteristic changes were noticed in blood glucose level as well as in lipid peroxidation and antioxidant status in normal rats treated with “PpEt” alone. We have also observed that the “PpEt” considerably reduced the blood glucose concentration in a similar extent to that of the reference drug glibenclamide (600 μg/kg bw) in alloxan induced diabetic rats. Our results thus suggested that the “PpEt” could be used as a safe alternative antihyperglycemic drug for diabetic patients.
