The chemical structure of Astragalus polysaccharide is complex and consists of an α-D-(1,4)-Glc and (1,6)-α-D-Glcp backbone, and a branch point at O-6. The molecular weight is approximately 3.01 × 105 Da from Mongolian Astragalus using low concentration of ethanol for precipitation and gel chromatography for purification. Spectral analysis results of 1H NMR and 13C NMR showed that the polysaccharide backbone has a 1,3-linked β-D-Gal residue and the branched portion has β-Glc, 1,6-linked α-Gal; 1,5-linked β-Xyl; 1,4-linked β-Gal; β-D-Gal, 1,2-linked α-Rha; and 1,2,4-linked α-Rha residues.
