| 摘 要： | 通过热水提取、离子交换层析和凝胶层析,从菊花(Chrysanthemum morifolium Ramat.)中分离得到一个新的多糖.根据糖组成分析、甲基化分析、高碘酸氧化、部分酸水解和NMR谱图分析,确定其结构如下:[→4)-Galp-(1→4)-Galp-(1→4)-Galp-(1→4)-Galp-(1→6)-Galp-(1]→F3L2Araf-(1→5)-Araf-(1→4)-Glcp-(1→4)-Glcp1→6 F3[→4)-Galp-(1→4)-Galp-(1→4)-Galp-(1→4)-Ga6p-(1→6)-Galp-(1]→n

| Abstract: | A novel polysaccharide was isolateded from Chrysanthemum morifolium Ramat. flowers by successive hot water extraction, anion-exchange chromatography and gel permeation chromatography. Sugar and methylation analysis, periodate oxidation, partial acid hydrolysis and NMR spectral analysis revealed that polysaccharide is composed of repeating units with the following structure: Araf-(1→5)-Araf-(1→4)-Glcp-(1→4)-Glcp 1 ↓ 6 ［→4-Galp-(1→4)-Galp-(1→4)- Galp-(1→4)- Galp-(1→6)- Galp-(1］→n |
