| Abstract: | 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 O2-· was respectively assayed by DPPH,salicylic acid and pyrogallol auto-oxidation methods.Result] FRUCTUS MORI polysaccharides had strong scavenging activity to DPPH·,·OH and O2-·,whose the highest scavenging rate 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. |
