Abstract: The antioxidant effects of Water Soluble Polysaccharides extracted from Portabella Mushroom Agaricus bisporus (WPPA) were studied by in vitro four different experiments: measuring reducing power, eliminating superoxide anion free radical experiment, eliminating hydroxyl free radical experiment, inhibiting mice erythrocyte hemolysis (MEH) and lipid peroxidation MDA induced by H2O2 experiment. The reducing power of WPPA was excellent. The scavenging abilities of superoxide radical and hydroxyl free radical were notable with IC50 value of 527 and 310 μg/mL, respectively. In addition, WPPA exhibited significant inhibitory actions on MEH and formation of MDA mediated by H2O2 with IC50 value of 700 and 541 μg/mL, respectively. The data obtained in the models in vitro clearly demonstrated the antioxidant potency of the WPPA.
