摘要
目的:探讨草苁蓉多糖的结构与功能的关系,填补草苁蓉成分研究的空白。方法:采用化学分析与气相色谱、质谱联机等仪器分析相结合的方法,对草苁蓉碱提多糖进行提取、组成和结构的研究。结果:草苁蓉经碱提取后,得到总糖含量分别为76.4%与54.8%的粗多糖 CP Ⅰ、CPⅡ;CP Ⅰ、CPⅡ的化学组成(摩尔比)分别为岩藻糖-葡萄糖-半乳糖-阿拉伯糖(3.09∶6.96∶4.58∶1)和岩藻糖-葡萄糖(1∶1.27)。结论:草苁蓉碱提多糖是岩藻糖、葡萄糖以1→2糖苷键相连,在葡萄糖-6位、岩藻糖-4位有分支点的多分枝结构。
Objective：Discussing the relationship between the structure and the function of the Boschniakia rossica polysaccharide, filling the blanks of composer research of Boschniakia rossica. Method： Adopting to the method of the combination of chemical analysis and the GC as well as the GC - MS analysis, making the research to the the constituents and structure of the Boschniakia rossica polysaccharide. Results：The polysaccharide CPⅠ and CP Ⅱ containing polysaccaride 76. 4% and 54. 8% had been extracted with alkaline from Boschniakia rossica, their sugar component and molar ratio were Fuc -Glc -Gal- Ara（ 3.09： 6. 96： 4. 58：1 ）, Fuc -Glc（ 1：1.27 ）in turn. Conclusion：The Boschniakia rossica polysaccharide extracted with alkailine have many branches. The main chain composed of two Glc and two Fuc of （1→2） linked sugars residues attached to Glc - 6 and Fuc - 4.
