Abstract

A water-insoluble glucan, TEINS has been isolated from the hot alkaline extract of an edible mushroom Termitomyces eurhizus. The total carbohydrate content of the polysaccharide fraction was found to be 98.4%, and it was found to contain only glucose as the monosaccharide constituent. On the basis of total acid hydrolysis, a methylation experiment, periodate oxidation and (13)C NMR experiment, the repeating unit of the polysaccharide was established as: -->3)-beta-D-Glcp-(1-->.

摘要

一种水不溶性葡聚糖,TEINS已从食用真菌黑柄炭角菌的热碱性提取物中分离出来。发现多糖部分的总碳水化合物含量为98.4%,并且发现其仅含有葡萄糖作为单糖成分。基于完全酸水解、甲基化实验、高碘酸盐氧化和(13)C NMR实验,确定该多糖的重复单元为:-->3)-β-D-葡萄糖-(1-->。
