Antioxidant Activities of Hydroalcoholic Extract of Ocimum sanctum Against Cadmium Induced Toxicity in Rats.

The present study was undertaken to analyze the antioxidant (both enzymic and nonenzymic) activities of leaves of Ocimum sanctum hydroalcoholic extract against cadmium induced damage in albino rats. Oral administration of cadmium as CdCl(2) (6.0 mg/kg body weight) led to significant elevation of lipid peroxidation (LPO) levels and significantly decreased Superoxide Dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx), Reduced Glutathione (GSH) and Vitamin C (Ascorbate) levels. Administration of Ocimum sanctum extract (100 mg/kg body weight, po) and (200 mg/kg body weight, po) before and after cadmium intoxication showed a significant decrease in LPO levels and significant increase in SOD, CAT, GPx, GSH and Ascorbate levels. The results suggest that oral administration of Ocimum sanctum extract provides significant protection against cadmium induced toxicity in Wistar albino rats.
