Pongamia pinnata (L.) Pierre (Fabaceae), popularly known as “Karanj” or “Karanja” in Hindi, and Indian beech in English, is a medium-sized glabrous tree. In the present study we report the antihyperglycemic activity of stem bark of alcohol extract of Pongamia pinnata (PPSBAE). Based on acute oral toxicity data, PPSBAE showed no mortality in normal mice up to 5,000 mg/kg. PPSBAE was administered as three doses (i.e., 100, 200, and 400 mg/kg) to diabetic mice, and the serum glucose level and body weight were measured. The onset of serum glucose reduction was observed at 2 h (130.32 mg/dl), peak at 4 h (151.79 mg/dl) and sustained at 6 h, but waned at 24 h. In the subacute study, maximum reduction (305.72 mg/dl) in serum glucose was observed at a dose of 400 mg/kg on day 28. An oral glucose tolerance test (OGTT) was carried out after administration PPSBAE (200 mg/kg) in non-diabetic mice previously loaded with 2.5 g/kg, per oral (p.o.) of glucose. The PPSBAE (200 mg/kg) showed increased glucose threshold in non-diabetic mice. These results suggest that the PPSBAE possesses antihyperglycemic activity.
