Separation and Antioxidant Properties in Vitro of Polysaccharide from Schisandra chinensis Fruits Wastes

Abstract:

The aim of this study is to find a way to reuse Schisandra chinensis fruits wastes after lignans extration.Polysaccharide tabled as SCP-0 was separated by hot-water extraction and ethanol precipitation,and then purified by polyamide column chromatography and Sephacryl S-300 HR column chromatography.After purity identification,the antioxidant activities of SCP-0 were investigated and the results showed a noticeable scavenging activity against hydroxyl radical and DPPH with IC50 of 14.5 mg/mL and 2.1 mg/mL respectively.However,superoxide anion scavenging activity of SCP-0 was hardly observed and certain ability of restraint on lard oxidation was observed.
