THE ANTIDIABETIC AND ANTIOXIDANT ACTIVITY OF COCCINEA GRANDIS VOIGT STEM EXTRACT IN STREPTOZOTOCIN INDUCED DIABETIC RATS

摘要

Objective: In the present study, the antidiabetic and antioxidant study of stem part of Coccinea grandis Voigt plant extracts in Streptozotocin induced diabetic rats were investigated. Materials and methods : Fifty four Wistar albino rats were used with nine groups and with six rats in each group. 45 mg/kg body weight streptozotocin was administered to group 2 to 9. Group 2 was diabetic control. Group 3 was given with glimepiride as standard drug. Group 4 and 5 were given petroleum ether extract 250 and 500 mg/kg respectively. Group 6 and 7 were given 250 and 500 mg/kg chloroform extract respectively. Group 8 and 9 were given 250 and 500 mg/kg hydro alcoholic extract respectively. Antidiabetic activity of the extracts was assessed by serum glucose level on glucose kit. Superoxide dismutase ( SOD), Catalase (CAT) and lipid peroxidation studies were assessed with histopathology. Result: The chronic study data on diabetic rats cleared the administration of all extracts significantly reduced blood glucose level and lipid peroxidation level with better antioxidant activity. Conclusion: From the study, the petroleum ether, chloroform and hydro alcoholic extracts of stem part of Coccinea grandis Voigt plant have shown antidiabetic and antioxidant potential.
