摘要: A new heteropolysaccharide, HEPF3. was isolated from the fruiting bodies of Hericium erinaceus. HEPF3 has a molecular weight of 1.9 x 104 Da and is composed of fucose and galactose in a ratio of 1:4.12. Compositional analysis, methylation analysis, together with H-1 and C-13 NMR spectroscopy established that HEPF3 consists of a branched pentasaccharide repeating unit with the following structure: [GRAPHICS] HEPF3 also contains a minor proportion of 3-O-methylrhamnose that is thought to terminate the polymer main chain.
