摘要
Abstract
A natural glucan HD-27 was isolated from Hedyotis diffusa Willd by alcohol precipitation, dialysis, anion-exchange and gel-permeation chromatography, The molecular weight of the glucan was 1800 as determined by ESIMS and showed [α]D20+165.5°(c0.50,H2O). Its structure was investigated by a combination of sugar composition analysis, methylation analysis, NaIO4 oxidation, and IR and NMR spectroscopy. The results showed HD-27 contained 11 glucose residues, which mainly composed of α-D-(1→4)-glucose with one β configuration reduced terminal residue.关键词
