To study the antioxidant capacity of the exopolysaccharides peptides (EPSP) from Ganoderma lucidum, four methods including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, reducing power assay, self-oxidation of 1,2,3-phentriol assay and hydroxyl radical assays were employed in vitro. The sample demonstrated scavenging capacity in a dose-dependent manner in every assay. Among them, the scavenging ability on hydroxyl radical of the sample was potent, which was more than two times that of ascorbic acid at each concentration (range of 1-5 mg ml-1). Especially, at the low level (1 mg ml-1), the scavenging effect of the sample (25.95±1.48%) was about 4.17 fold that of ascorbic acid (6.22±0.38%). The findings obtained in this work showed that EPSP from G. lucidum broth might be good sources for antioxidant-related and healthy functional food additive.
