The antioxidant properties of water extracted polysaccharides (PW), 1%(w/v) NaOH extracted polysaccharides(PN1), and 5%(w/v) NaOH extracted polysaccharides (PN5) were assessed in this paper. PW showed good capability ofscavenging H2O2, anti-lipid peroxidation, reduction power, and scavenging 1,1-diphenyl-2-picrylhydrazyl (DPPH). Themaximum values were all observed at the dose of 1mg/mL sample. As far as the antioxidant activities of PN1 wereconcerned, the capability of scavenging superoxide radical, chelating metal, and total antioxidation showed higher than thoseof PN5. When polysaccharide concentration was 1mg/mL, the 3 index described above were attached 71.8%, 51.6%, and446.3µM Trolox equivalent, respectively. With respect to PN5, higher capabilities of scavenging hydroxyl free radicals wereobtained while the peak of 84.8% was observed at the concentration of 1.0mg/mL. Moreover, the concentration-dependentinfluences were characterized in all cases.
