Antihyperglycemic and Antioxidant Activities of Medicinal Plant Stereospermum suaveolens in Streptozotocin-induced Diabetic Rats:


The ethanol extract of Stereospermum suaveolens (EESS) bark was evaluated for its antihyperglycemic in addition to antioxidant effects in streptozotocin (STZ)-induced diabetic rats by acute and subacute models at dose levels of 200 and 400 mg/kg body weight, given orally. The ethanol extract showed a significant reduction in fasting blood glucose levels when compared to the standard drug, oral Glibenclamide (0.5 mg/kg body weight). The serum of rats treated with ethanol extract showed decreased levels of serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, serum alkaline phosphatase, bilirubin, creatinine, urea, total cholesterol, triglycerides, and increased level of total proteins. EESS showed reduction in thiobarbituric acid reactive substances level and significantly increased the body weight (P < .001), glycogen, reduced glutathione, superoxide dismutase, and catalase activities, compared with STZ diabetic control in a dose-dependent manner. This finding shows that the ethanol extract of Stereospermum suaveolens exhibits potent antihyperglycemic and antioxidant properties.
