摘要
从曾用水提取过水溶性多糖的安络小皮伞残渣中用稀碱液提取了二种水溶多糖 B_1和B_2。它们分别给 Sepharose 4B 柱,2B 柱层析,超离心分析,醋酸纤维薄膜电泳鉴定,表明 B_1和 B_2均为纯多糖。采用气相色谱,红外光谱,淀粉酶解,甲基化分析等方法确定了它的基本结构。
The water soluble polysaccharides BB are isolated by alkaline extra- ction from the Marasmius androsaceus L.:Fr.residue after water extraction.Theirs homogeneity are proved by gel filtration on sepharose 4B and 2B column,ultracentri- fugal analysis,cellulose acetate film electrophoresis.The structures of B_1 and B_2 have been determined by GC,IR,^(13)C-NMR,~1H-NMR,periodate oxidation,Smith degradation,amylase degraded,methylation analysis,GS-MS etc.
