摘要：
A novel polysaccharide (MFP1P) was isolated from Fructus Mori, followed by purification via DEAE-52 cellulose and 27 % ethanol fraction. The MFP1P had the molecular weight of 56.78 kDa and the total sugar content of 93.32±0.54 %. And the MFP1P is mainly composed of glucose, galactose, galacturonic acid and mannose with molar ratio of 66.62 %, 13.94 %, 18.24 % and 1.20 %, respectively. MFP1P was mainly composed of →3)-α-D-Gal (1→, β-D-Man-(1→ and →6)-α-D-Glc (1→ glycosidic bond and showed a spherical chain conformation with uniform distribution in solution. The MFP1P exhibited great antioxidant activity with oxygen-free radical absorption capacity (ORAC) values of 291.63±6.81 μmol TE/g and MDA IC50 of 0.289±0.022 mg/mL. © 2020 Elsevier Ltd
