摘要: A water soluble beta-glucan (GLSWA-I) with a weight average molecular weight similar to 1.57 x 10(5) g/mol, isolated from the aqueous extract of the broken cellular wall Ganoderma lucidum spores, was purified by anion exchange and gel-permeation chromatography. The immunological activity test in vivo showed that GLSWA-I could significantly promote dinitrochlorobenzene (DNCB) induced delayed-type ear swelling in mice. Based on the monosaccharides composition analysis, methylation analysis, IR, 1D and 2D NMR spectroscopy, the repeating unit of polysaccharide GLSWA-I was elucidated as follows:
