| 摘 要： | 苦瓜粗多糖(MCP)经DEAE-纤维素凝胶柱层析及Sephadex G-100凝胶柱层析纯化后,得到多糖组分MCP Ia,经紫外光谱分析及醋酸纤维素薄膜电泳法纯度检验,结果表明MCP Ia是单一组分。HPLC分析其单糖组成为L-鼠李糖、D-木糖、D-果糖和D-半乳糖,单糖物质的量比为4.4:2.3:1:5.7,另外,MCP Ia还可能含有葡萄糖;MCP Ia红外光谱表明:苦瓜多糖存在分子内和分子间的氢键,分子中存在C—H键伸缩振动,存在—OH的变形振动,存在呋喃糖苷吸收峰,是典型的多糖类化合物。

| Abstract: | The crude polysaccharide(MCP) extracted from the fruits of Momordica charantial was subjected to DEAE-cellulose column chromatographic separation and Sephadex G-100 column chromatographic fractionation and a polysaccharide fraction with a high ability to scavenge superoxide anion and hydroxyl free radicals,named MCP Ia,was obtained.According to UV spectroscopic analysis and cellulose acetate membrane electrophoresis,MCP Ia was a single composition.Its monosaccharide composition was determined by HPLC to con... |
