Objective: The present study was carried out to investigate the effects of Punica granatum peel methanolic extract (PGPE) on cerebral cortex (CC) and Hippocampus (HC) brain antioxidant defense system and markers of lipid and protein oxidation in alloxan induced diabetic rats. Methods: Oral administration of PGPE (75 and 150 mg of kg body weight) for 45 days resulted in significant reduction in blood glucose levels. Results: Supplementation of diabetic rats with PGPE showed increased activities of SOD and GPx with concomitant decrease in MDA and PC content. Region-specific changes were more evident in the HC when compared to CC. Conclusions: The present study indicated that PGPE can ameliorate brain oxidative stress in alloxan induced diabetic rats by up regulating antioxidant defense mechanism by attenuating lipid and protein oxidation. PGPE thus may be used as a potential therapeutic agent in preventing diabetic complications in the brain.
