title: [Studies on polysaccharide of Rheum palmatum L].
abstract: Two homogeneous acidic heteroglycans DHP-1 and DHP-2 were obtained from the root of Rheum palmatum, the mean molecular weights being 11 x 10(4) and 2.5 x 10(4) respectively. It was identified by TLC and GC that both heteroglycans contain the same main residues of glucose, galactose, arabinose, rhamnose, lyxose, xylose, glucuronic acid and galacturonic acid.
