[Objective] To study the scavenging activity of FRUCTUS MORI polysaccharides to free radical in vitro.[Method] The ability of FRUCTUS MORI polysaccharides to scavenge DPPH·,·OH and O-2· was respectively assayed by DPPH,salicylic acid and pyrogallol auto-oxidation methods.[Result] FRUCTUS MORI polysaccharides had strong scavenging activity to DPPH·,·OH and O-2·,the highest scavenging rate of which to the above 3 free radicals was 90.01%,76.40% and 49.85% respectively.[Conclusion] FRUCTUS MORI polysaccharides had strong scavenging activity to free radicals in vitro.
