A polysaccharide named as AMP-1 was isolated from the root of Atractylodis macrocephalae Koidz, and purified by ethanol fractionation and gel filtration. The homogeneity of AMP-1 was determined by HPLC and capillary...
The synthesis of phosphorylated Achyranthes bidentata polysaccharide (P-AbPS) was reported based on different strategies. The P-AbPS with high degree of substitution (D.S. > 0.5) was obtained when phosphorus oxychlori...
