    日期:1954.1.1
    the most part at least without Walden inversions or other change, because hydrogenation of the sirupy product reduced it in more than 80% yield to crystalline methyl glucoside. The product from methyl-β-glucoside tetranitrate consisted of the 2,3,6-trinitrate (28%), the 3,6-dinitrate (17%), and an unidentified trinitrate (8%) which might have been a mixture.The structures of the first two compounds
    甲基葡糖苷四硝酸酯在室温下与溶解在无水吡啶中的过量羟胺碱剧烈反应。在 20 分钟内释放出由 91% 的氮气组成的气体,每摩尔的气体量为 1.25 至 1.3 摩尔。在接下来的 12 小时内只会多一点。原始四硝酸酯中大约 1.35 摩尔的硝酸根基团已被羟基取代,大部分至少没有瓦尔登反转或其他变化,因为糖浆状产物的氢化将其降低为结晶甲基葡糖苷的 80% 以上产率。甲基-β-葡萄糖苷四硝酸酯的产物由 2,3,6-三硝酸酯 (28%)、3,6-二硝酸酯 (17%) 和可能是混合物的不明三硝酸酯 (8%) 组成。前两种化合物的结构通过制备完全甲基化的衍生物、将后者脱硝并鉴定所得已知的、部分甲基化的甲基-β-葡萄糖苷来确认。甲基-β-葡萄糖苷-3,6-二硝酸酯的新合成...

    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.
