摘要：

The cushaw polysaccharide was obtained by hot water extraction. Two sulfated cushaw polysaccharides (SP1 and SP2) with different degrees of substitution and two phosphorylated cushaw polysaccharides (PP1 and PP2) with different degrees of substitution were prepared, respectively. Their structures were characterized by IR,C-13 NMR and P-31 NMR spectra, respectively. It indicated that the introduction of phosphate groups helped remove hydroxyl radicals. All the derivatives enhanced the scavenging of superoxide anions. It would provide a good basis for studying the antioxidant activity of cushaw polysaccharide and their derivatives.
