| 摘 要： | 老龙皮经热水提取,乙醇沉淀及进一步精制得LOK(Lobaria kurokauae)多糖,经SephadexG-75柱层析为一组均一多糖,糖含量为82.4％。气相色谱分析含有鼠李糖、阿拉伯糖、木糖、甘露糖、葡萄糖、半乳糖。其克分子比为1.00:1.34:1.12:10.13:6.99:6.47。经Sephadex G-200柱层析测定,平均分子量为1.5×10~4。经高碘酸氧化,Smith降解,有甲酸、丙三醇、丁四醇生成,红外光谱在842cm~(-1)有吸收,说明LOK多糖结构主要以α(1→4)、a(1→6)苷键连接而成的杂多糖。

| Abstract: | LOK polysaccharide is isolated from Lobaria kurokauae. By chromatography, LOK is shown to be sing substance. By gas chromatography analysis, LOK composes of rhamnose, arabinose, xylose, mannose, glucose and galactose. Their molecule ratio is about 1.00:1.34:1.12:10.13:6.99:6.47. Its mean molecule weight is estimated to be 1.5 x 10(4), its main chain is joined by a (1-->4) and a (1-->6) glucosidic linkages. |
