Abstract

Heteropolysaccharides isolated from liquid cultures of nine Tremella species contained 0.3 to 1.2% protein, 2.7 to 5% ash, 0.9 to 3.4% acetyl groups, 76.5 to 84.2% carbohydrates and trace amounts of starch. The polysaccharides in aqueous solution were slightly acidic (pH 5.1 to 5.6). They consisted of the following monomeric sugars: fucose, ribose, xylose, arabinose, mannose, galactose, glucose and glucuronic acid. The backbones of the polysaccharide structures consisted of α-(1→3)-links while the side chains were β-linked.

摘要

从9种银耳属物种的液体培养物中分离出的杂多糖含有0.3%至1.2%的蛋白质、2.7%至5%的灰分、0.9%至3.4%的乙酰基、76.5%至84.2%的碳水化合物以及微量淀粉。水溶液中的多糖呈弱酸性（pH值为5.1至5.6）。它们由以下单糖组成：岩藻糖、核糖、木糖、阿拉伯糖、甘露糖、半乳糖、葡萄糖和葡萄糖醛酸。多糖结构的主链由α-(1→3)连接组成，而侧链则是β连接。
