摘要
The structure of a saccharide component (Abs),with pronounced activity of improving immunity system,isolated from the root of Achyranthes bidentata Blume,a traditional Chinese herbal medicine,was studied.Based on 13C NMR,HPLC,and methylation analyses,Abs was shown to be a mixture of short-chain fructans with an average dp of 8,containing more (2→6) than (2→1) linked β-D-fructofuranosyl residues,with branching at O-6 or O-1 of 18% of the D-fructofuranoeyl residues.
