  • Title: [Studies on isolation, purification and structure of polysaccharide RHG from Hedysarum polybotrys Hand.-Mazz].
    Author: Liu FM, Li ZX, Meng YF, Chen YZ.
    Journal: Yao Xue Xue Bao; 1997 Aug; 32(8):603-6. PubMed ID: 11596310.
    Abstract:
    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.
