To evaluate the antihyperglycaemic activity of the ethanol extract of roots of Vetiveria zizanioides (L.) Nash, in alloxan induced diabetic rats. Alloxan monohydrate (150 mg/kg) was administered to Wister albino rats via the interperitoneal route. The diabetic rats were then placed into 6 groups, following stabilization of hyperglycaemia. The first group was untreated; second group received a reference standard, glibenclamide (10 mg/kg), and the next four groups received ethanol extract of V. zizanioides roots at the doses of 100, 250, 500 &750 mg/kg, respectively each day. Treatment was provided via the oral route for 28 days and fasting sugar level was monitored over this period. Acute toxicity (oral and interperitoneal) studies as well as phytochemical screenings of the extracts were carried out. It was observed that ethanol extract of V. zizanioides (100, 250, 500 & 750 mg/kg p.w.o) significantly reduced the bloodglucose level at the end of 28th days in alloxan induced diabetes rats. The antihyperglycaemic effects were compared with those of glibenclamide (10 mg/kg p.w.o), the standard reference hypoglycaemic agent. The present study indicates that ethanol extract of V. zizanioides root posses better antihyperglycaemic activity compared to other extracts of it in both normal and alloxan induced diabetic rats. The study provides a proof for the ethno medical claims and reported biological activities of V. Zizanioides in respect to its very good therapeutic and antidiabetic potential.
