Abstract
AIM: To study the physicochemical properties and the structure of Achyranthes bidentata polysaccharide (AbPS). METHODS: AbPS was isolated from the roots of Achyranthes bidentata Bl., and purified by gel filtration chromatography. The distribution of the molecular weight of AbPS was determined by ESI-MS. The structure of AbPS was deduced by methylation analysis, reductive-cleavage and 13CNMR spectroscopy. RESULTS: AbPS was shown to compose of fructose residues and glucose residues and the molar ratio was 8:1. AbPS contain 2,1-linked fructose residue, 2,1-linked fructose residue, 1,2,6-linked fructose residue, terminal fructose residue and terminal glucose residue. CONCLUSION: AbPS is a fructan and belong to graminan.
