The antioxidant activity of the purified polysaccharides was evaluated in vitro by 1,1-diphenyl-2-picrylhydrazyl
(DPPH) free radical scavenging assay, self-oxidation of 1,2,3-phentriol assay. Those various antioxidant activities were
compared to standard antioxidants vitamin C and BHT. It was found that the scavenging effects of the purified polysaccharides increased with measuring concentration.
