Annapurani, S2017-03-072017-03-072010https://ir.avinuty.ac.in/handle/avu/1917Cells are equipped with enzymatic and non enzymatic antioxidative mechanism that play an important role in elimination o f free radicals SOD, Catalase, Glutathione peroxides and reductase involved in the clearance o f superoxide and HjOj.Hence the present study was carried out to evaluate the antioxidant levels and observed catalase (60.21U/mg protein), superoxide dismutase (4.49U/mg protein), glutathione peroxidase (3.3U/mg protein), glutathione reductase (10.8U/mg protein)and glutathione -s- transferase (2083.32U/mg protein) in the liver ofthe experimental mice treated with protein fraction o f Cynodon dactylon. The results were found to be statistically significant when compared to their controls.
