A water-soluble polysaccharide, RHG, was isolated from the roots of Hedysarum polybotrys Hand.-Mazz. It was shown to be homogeneous by electrophoresis and gel filtration. Its average molecular weight was estimated to be 1.4 x 10(4). Methylation analysis, periodate oxidation, Smith degradation, IR, NMR and KI-I2 reaction showed that RHG is a (1-4) linked alpha-D-glucan to which the glucosyl side chains are attached at O-6 of the glucosyl residues of the main chain.
从多序岩黄芪（Hedysarum polybotrys Hand.-Mazz.）根部分离得到一种水溶性多糖RHG。经电泳和凝胶过滤表明其具有均一性。估计其平均分子量为1.4×10⁴。甲基化分析、高碘酸盐氧化、史密斯降解、红外光谱、核磁共振和碘化钾-碘反应表明，RHG是一种（1-4）连接的α-D-葡聚糖，其葡糖基侧链连接在主链葡糖基残基的O-6位上。
