Aim of the Study: The aim is to evaluate the hypoglycemic and antidiabetic effects of aqueous and CH2Cl2/CH3OH stem bark extracts of Pterocarpus soyauxii Taub in normal and diabetic rats. Materials and Methods: Streptozotocin (STZ)-induced diabetic and normal adult Wistar rats were orally administered with aqueous and CH2Cl2/CH3OH plant extracts of P. soyauxii at various doses (38{\textendash}300 mg/kg) in a single administration. In addition, STZ-induced diabetic rats received prolonged daily administration for 14 days. Glibenclamide (GB) (10 mg/kg) was used as reference treatment. In acute test, fasting blood glucose was followed for 5 h. In subacute test, body weight, food and water intakes, and blood glucose were followed weekly and serum biochemical parameters evaluated after 14 days treatment. Results: Acute administration of aqueous and CH2Cl2/ CH3OH stem bark extracts moderately decreased fasting blood glucose compared to GB, significantly in normal rats (P \< 0.05 to P \< 0.01) but, as GB, not significantly in diabetic rats. Prolonged treatments in diabetic rats with aqueous and CH2Cl2/CH3OH extracts reduced blood glucose to an extent, respectively, superior or similar to GB. Moreover, P. soyauxii also significantly (P \< 0.01) reduced weight loss, and diabetes increased serum triglycerides, total cholesterol, and transaminases (alanine aminotransferase/ aspartate aminotransferase) elevations. Conclusion: P. soyauxii Taub stem bark extracts have possible value for antidiabetic oral medication.
