摘要
从安络小皮伞水溶性多糖中分离纯化得一甘露聚糖 FP_1。分子量约为24万。经红外光谱、^+H-NMR 谱和亲和层析指明为β-甘露聚糖。结构分析采用高碘酸氧化、Smith 降解、完全甲基化 GC、GC-MS 与^(13)C-NMR 分析,分子的主链是β-D-(1→6)连接的甘露糖,支链为β-(1→3),β(1→2)甘露糖,分别连接在主链的 O-3和 O-2上。
A mannan FP_1 has been isolated and purified from the water soluble polysaccharide mixture extracted from mycelia of Marasmius androsaceus.The mole- cular weight abount 240000.It is β-D-mannan examined by I.R.and affinity chro- matography.The structure of FP_1 has been determinated by periodate oxidation, Smith degradation,methylation,GC,GC-MS etc.The main chain of the molecules was composed of β-D-(1→6) linked mannose,side chain was β-(1→3) and β- (1→2) linked mannose attached to 0-3 and 0-2 of main chain respectively.
