皂角菌多糖的研究

Studies on the Polysaccharide of Fomes marginatus

采用水提、醇沉、Sevage法除蛋白质,重结晶精制得皂角菌多糖。经检测该多糖为均一组分,其平均分子量为1.5×10^(4-)多糖经完全水解,高碘酸氢化,Smith降解,经红外光谱分析显示其由β-(1→4)、(1→6)葡聚糖糖甙键组成。

This paper reports that polysaccharose was prepared by ethanol precipitation of water extracted and by deproteinization with sevage method, purification obtain Fames marginatus. The polysaccharose which was determined by using sephadex-G, PAGE, ACTME, TLC and PC is single composition. [α]D20 = 28. 89, it content of polysaccharose is 22. 62 percent. It was hydrolied of periodate oxidation, smith degradation and IR analysis, the results show that the main chain is composed of B-(1→4), (1→6)linkage.
