  • Polyasaccharide polyol, process for preparation thereof and anti-tumor agent
    申请人:TOYO SODA MANUFACTURING CO., LTD.
    公开号:EP0121146A2
    公开(公告)日:1984-10-10
    Described is a polysaccharide polyol derived from Volvariella volvacea, which is comprised of the following three types of recurring units. wherein D-Glu is D-glucopyranosyl residue, each number represents the linkage position, X is HOCH2CH(CH20H)-O-CH(CH20H)-O-[Formula A) or D-glucopyranosyl and Y is -CH2-CH(CH20H)-O-CH(CH20H)-O- or D-glucopyranosyl, at least a part of X in the recurring units II and III is that of formula A, and, the average number of III is about 4-12 and the average number of the sum of II and III is about 16-23, per 100 of the sum of I, II and III. The polysaccharide is prepared by extracting Volvariella volvacea with an aqueous alkali solution and oxidising and then reducing the soluble fraction to cut parts of C-C bonds of side chains. The polysaccharide is useful as an anti-tumour agent.
