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 ((1)H, (13)C, DEPT-135, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC), the structure of the repeating unit of the polysaccharide was established as This glucan stimulates macrophages, splenocytes, and thymocytes.
从可食用蘑菇佛罗里达侧耳（Pleurotus florida）的子实体热水提取物中分离出的一种免疫增强多糖，经鉴定仅由 d-葡萄糖作为单糖组成。根据完全酸水解、甲基化分析、高碘酸氧化、Smith 降解和 NMR 实验（1H、13C、DEPT-135、DQF-COSY、TOCSY、NOESY、ROESY、HMQC 和 HMBC），多糖重复单元的结构确定为该葡聚糖可刺激巨噬细胞、脾细胞和胸腺细胞。
