Black tea ameliorates aflatoxin-induced lipid peroxidation in the kidney of mice.

Oral administration of 25 and 50 mg of aflatoxin in 0.2 mL olive oil/animal/day for 30 days caused dose-dependent and significantly higher lipid peroxidation in the kidney of aflatoxin-treated mice than in the controls. The levels of non-enzymatic antioxidant such as glutathione as well as the enzymatic antioxidants such as superoxide dismutase, glutathione peroxidase and catalase were significantly lower in the kidney of aflatoxin-treated mice than in the controls. Black tea extract (2%) treatment significantly ameliorates aflatoxin-induced lipid peroxidation, which could be due to higher enzymatic and non-enzymatic antioxidants in the kidney of mice as compared with that given aflatoxin alone. These findings suggest that black tea extract treatment significantly ameliorates aflatoxin-induced lipid peroxidation in the kidney of mice.
