illustrated the scavenging rate of all samples showing scavenging ability of ABMPs on DPPH radicals. With the extension of detecting concentration, the rates of all samples tended to ascending drastically. Among three polysaccharides, ABMP-F exhibitedhigher DPPH radical scavenging rate than ABMP-V and ABMP-A at every concentration point, which implied that ABMP-F has the best DPPH radical scavenging ability and ABMP-A the worst. Considering the changes of the chemical composition of the three ABMP samples, it can be concluded that the DPPH radical scavenging abilities were influenced by different drying methods.
