摘要：

Three polysaccharides, namely exopolysaccharide (EPS), water-extracted mycelial polysaccharide (WPS) and sodium hydroxide-extracted mycelial polysaccharide (SPS), from the endophytic fungus Fusarium oxysporum Dzf17 were investigated for their in vitro antioxidant activities. Among them, SPS was the most active antioxidant component, and WPS exhibited moderate antioxidant activity. The median effective concentration (EC50) values of the polysaccharides were 162.38 mu g/ml (for WPS), 63.37 mu g/ml (for SPS) by DPPH radical scavenging activity assay, and 54.54 mu g/ml (for WPS) and 44.91 mu g/ml (for SPS) by using ferrous ions chelating activity assay. The polysaccharides from F. oxysporum Dzf17 could be an alternative source as the antioxidant components.
