| Abstract | ||||
| Tea is the second most popular drink in the world after water, and many studies have highlighted the effects of drinking tea. Therefore, the aim of this study was to explore the effects of white tea extract on the antioxidant enzymes activity including superoxide dismutase (SOD), glutathione peroxidase (GSH-px), and catalase (CAT). A significant decrease was observedin serum and liverSOD, GSH-px, and CAT activities in the diabetic control rats compared with the nondiabetic control ones. However, a significant increase in SOD, GSH-px, and CAT activities (serum and liver) was observed in the diabetic groups treated with white tea extract or Glibenclamide as compared to the diabetic control group. In conclusion, the present findings indicated that white tea extract has an enhancing effect on the antioxidant enzyme activities (SOD, CAT, and GSH-px) in STZ-induced diabetic rats | ||||
