摘要：
An immunoenhancing polysaccharide isolated from the hot water extract of the fruiting bodies of an edible mushroom Pleurotus florida, cultivar Assam Florida, was found to consist of only D-glucose as a monosaccharide constituent. On the basis of total acid hydrolysis, methylation analysis, periodate oxidation, Smith degradation, and NMR experiments (H-1, C-13, DEPT-135, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC), the structure of the repeating unit of the polysaccharide was established as [GRAPHICS] This glucan stimulates macrophages, splenocytes, and thymocytes.
