摘要：

The water-soluble Dictyophora indusiata polysaccharides (DIP) were extracted from the fruiting body of D. indusiata. The structural features of purified DIPs I and II were investigated. The results indicated that DIP I was composed of glucose (Glc) and mannose (Man) with molecular weight of 2100 kDa, while DIP II comprised of xylose (Xyl), galactose (Gal), glucose (Glc) and Man with molecular weight of 18.16 kDa. The glycosidic linkage of DIP I was composed of -> 1)-Glc-(6 ->: -> 1)-Man-(3,6 -> with the ratio of 5.6:1.0, while DIP II was composed of -> 1)-Glc-(6 ->: -> 1)-Man-(3,6 ->: -> 1)-Xyl-(5 ->: -> 1)-Gal-(3 ->: -> 1)-Gal-(6 ->: with the ratio of 4.9: 15.5: 7.8: 1.0: 5.7. DIP significantly (P < 0.05) decreased the malondialdehyde (MDA), lipofuscin levels and increased the superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activities of mice. The strong in vivo antioxidant activity indicated DIP had great potential as functional food. (C) 2011 Published by Elsevier Ltd.
