| 摘 要： | H3, a homogeneous acidic polysaccharide was obtained from the seeds of Cuscuta chinensisLam. Its structure was characterized for the first time by chemical and spectroscopic methods to be a highly branchedheteropolysaccharide with mean molecular weight of more than lxl0^6. It was composed of 1,6-1inked-β-D Galp, 1,4-linked-β-D Galp, 1,4-1inked-β-D GalA, 1,3,6-1inked-β-D Galp and 1,2,4-1inked Rhap, with branching points at O-2or 0-4 of 1,2,4-1inked Rhap and 0-3 of 1,3,6-1inked-β-D Galp. Its side chains included 1-1inked Araf, 1,5-1inked Arafand 1,3,5-1inked Araf at O-3 of 1,6-1inked Galp in the main chain.
