Abstract

This study was conducted to evaluate the anti-diabetic and antioxidant effects of hydroalcoholic pomegranate peel extract (APE) in alloxan-induced diabetes rat models. We divided 60 rats into the following six equal groups (n = 10): Healthy control; diabetic control (100 mg/kg alloxan); sham + glibenclamide (10 mg/kg); diabetic + glibenclamide (10 mg/kg); sham + APE (200 mg/kg) and diabetic + APE (200 mg/kg). After 8 weeks, kidneys were taken out for biochemical and molecular studies. Following APE treatment, biochemical parameters including malondialdehyde (MDA), and glutathione (GSH), glutathione peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD) significantly induced in the treated group as compared with the control group (p < 0.05). Also, gene expression of GPx (3-fold), CAT (2.6-fold), and SOD (1.5-fold) were increased as compared to controls (p < 0.05). Overall, our results indicated that pomegranate can be used as an antioxidant agent to reduce complications from diseases associated with oxidative stress.
