摘要：

A water-soluble fucogalactan (CMP3), with a molecular mass of 1.03 x 10(4) Da as determined by high-performance size-exclusion chromatography (HPSEC), was obtained from the crude intracellular polysaccharide of Coprinus comatus mycelium. Its chemical structure was characterized by sugar and methylation analysis along with H-1 and C-13 NMR spectroscopy, including NOESY and HMBC experiments for linkage and sequence analysis. The polysaccharide is composed of a pentasaccharide repeating unit with the following structure: [GRAPHICS] (c) 2006 Elsevier Ltd. All rights reserved.
