A water-soluble polysaccharide, (Fr. I) isolated from the aqueous extract of an edible mushroom, Volvariella diplasia, is composed of D-glucose, D-mannose, and D-galactose in a molar ratio 3:1:1. Compositional analysis, methylation analysis, periodate oxidation study, Smith degradation, and NMR studies (1H, 13C, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC) revealed the presence of the following repeating unit in the polysaccharide: [Formula: see text].
从食用菌双孢草菇的水提取物中分离出一种水溶性多糖（级分I），其由D-葡萄糖、D-甘露糖和D-半乳糖以3:1:1的摩尔比组成。组成分析、甲基化分析、高碘酸盐氧化研究、史密斯降解和核磁共振研究（1H、13C、双量子滤波相关谱、全相关谱、核欧沃豪斯效应谱、旋转框架核欧沃豪斯效应谱、异核多量子相干谱和异核多键相关谱）表明该多糖中存在以下重复单元：[分子式：见正文]
