摘要： A new alpha-D-glucan (HEPF5), with a molecular weight of 4.23 x 10(5) Da as determined by high-performance liquid chromatography, was isolated from the water extract of the fruiting bodies of Hericium erinaceus. Its chemical structure was characterized by sugar and methylation analysis along with infrared (IR), (1)H and (13)C nuclear magnetic resonance spectroscopy, including correlated spectroscopy, total correlation spectroscopy, heteronuclear multiple quantum correlation spectroscopy and nuclear Overhauser enhancement spectroscopy experiments for linkage and sequence analysis. The polysaccharide is composed of a multibranch tetrasaccharide repeating unit with the following structure: [GRAPHICS]
