Abstract

Objective: To evaluate the effect of extract of Murraya paniculata Linn. (Family - Rutaceae) on blood glucose, cholesterol, triglyceride and lipid level and antioxidant status in alloxan induced diabetic and non-diabetic rats. Methods: hydro-alcoholic extract of M. paniculata leaves (100, 200 and 400 mg/kg) was administered orally for 14 days and its effect on blood glucose, cholesterol, triglycerides and lipid level were estimated in serum. Liver free radical (lipid peroxidation, LPO) and antioxidant (Super oxide dismutase, SOD; catalase, CAT; and reduced glutathione peroxidase, GPx) were also measured after 14 days treatment with extract. Glucose level in non-diabetic rats was estimated after 21 days treatment with M. paniculata extract. Results: Oral administrations of M. paniculata extract (100, 200 and 400 mg/kg) for 14 days significantly reduced the levels of blood glucose, cholesterol, and triglyceride and lipid level. Liver free radical (LPO) significantly reduced and antioxidants (SOD, CAT and GPx) status significantly increase after 14 days treatment of extract in diabetic rats. M. paniculata 200 and 400 mg/kg significantly decrease glucose level in non-diabetic rats after 21 day and caused hypoglycemia in normal rats. Conclusions: M. paniculata leaves extract posses hypoglycemic effect in oxidative stress condition and also in non-diabetic condition. Hypoglycemic action may be by potentiating of the insulin effect by increasing either the pancreatic secretion of insulin from beta cells of islets of langerhans or its release from the bound form. M. paniculata could be a potential source of hypoglycemic agent with antioxidant properties.
