Abstract OBJECTIVE: To investigate the antidiabetic effect of aqueous extract of Merremia tridentata (M. tridentata) root (MTRAE) in normal, glucose-loaded hyperglycemic and streptozotocin (STZ)-induced diabetic rats. METHODS: Oral administration of MTRAE at the doses of 50, 100 and 150 mg/kg was studied in normal, glucose-loaded and STZ-diabetic rats. The three doses caused significant reduction in blood glucose levels in all the models. RESULTS: The effect was more pronounced in 100 and 150 mg/kg than 50 mg/kg. MTRAE also showed significant increase in serum insulin, body weight and glycogen content in liver and skeletal muscle of STZ-induced diabetic rats while there was significant reduction in the levels of serum triglyceride and total cholesterol. MTRAE also showed significant antilipidperoxidative effect in the pancreas of STZ-induced diabetic rats. The antidiabetic effect of M. tridentata was compared with glibenclamide, a well known hypoglycemic drug. CONCLUSIONS: The results indicate that aqueous extract of M. tridentata root possesses significant antidiabetic activity. Copyright © 2012 Hainan Medical College. Published by Elsevier B.V.
