The aim of this investigation was to study the antioxidant status of Streptozotocin induced diabetic rats which were treated with methanolic stem extract of Coscinium fenestratum. Diabetes was induced by administering STZ by intra femoral vein injection at a dose of 40mg/kg body weight. Methanolic extract of Coscinium fenestratum was administered to the rats at a dose of 200 mg/kg body weight for a period of two weeks. The antioxidant status of the treated animals were assessed by measuring the activity of liver enzymes such as Catalase, Super oxide dismutase and Glutathione S Transferase. Levels of these antioxidant enzymes decreased in untreated diabetes compared to normal values. Administration of methanolic fractions of Coscinium fenestratum in STZ induced diabetic rats reversed these changes. Oxidative stress plays a major role in generation of free radicals in the pathogenesis of diabetes and its complications. Our findings suggest that C. fenestratum methanolic extract exerted anti-hyperglycemic activity by combating the oxidative stress, improving the glycogen content and by activating the carbohydrate metabolizing enzyme Hexokinase. The presence of Berberine and other phenolic compounds in the stem extracts may be responsible for this action.
