摘要
用GC,IR,NMR,GC-MS及高碘酸氧化,Smith降解,甲基化分析,部分酸水解等方法确定了一个新的碱提水溶小皮伞多糖的一级结构:分子主链α-D-(1→2)Man,支链α-(1→4),α-(a→6)Glc,且均连在主链的0─6上。
The structure of a new polysaccheride(B_3) extracted by alkaline solution from the marasmius androsaceus L:Fr. has been determined by GC, IR, NMR , GC-MS, Periodate oxidation, Smith degradation, methylation, Partial acidhydrolysis, etc. The main chain of molecules was α-D- (1→2)Man. Side chain was α- (1→4)and α- (1→6) linked Glc attached to 0-6 of main chain respectively.
