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.
从掌叶大黄根部分离得到两种均一的酸性杂聚糖DHP-1和DHP-2，平均分子量分别为11×10⁴和2.5×10⁴。通过薄层层析（TLC）和气相色谱（GC）鉴定，两种杂聚糖均含有相同的主要残基，包括葡萄糖、半乳糖、阿拉伯糖、鼠李糖、来苏糖、木糖、葡萄糖醛酸和半乳糖醛酸。
