The present study was undertaken to examine the inhibitory effect of the green tea (Camellia sinesis) on cadmium chloride induced antioxidant activity in liver. The levels of lipid peroxidation were assessed by estimating TBARS and lipid peroxidation and the antioxidant levels were assessed by estimating the levels of GSH, SOD, CAT and GPx. Significant increases was observed in the levels of TBARS and hydroperoxide in CdCl2 treated rats. These levels were significantly decreased in CdCl2 and Green tea (Camellia sinesis) extract treated rats. Further enzymatic (SOD, CAT and GPx) and non-enzymatic (GSH) antioxidants were significantly decreased in CdCl2 treated rats.
