从仙人掌茎中提取多糖,并采用SuperdexTM200、SaphacrylS-100HR、Sephadex G-100凝胶柱层析法分离得到2个多糖组分(OPSⅠ和OPSⅡ),它们均为化学均一物质;用气相色谱法分析仙人掌多糖OPSⅠ和OPSⅡ的单糖组成,结果表明:OPSⅠ主要由鼠李糖、葡萄糖和半乳糖组成;OPSⅡ主要由岩藻糖、木糖和葡萄糖组成。
Polysaccharides were extracted from cactus stems and polysaccharides (OPSⅠ and OPSⅡ) were separated by SuperdexTM200, Saphacryl S-100HR and Sephadex G-100 gel column chromatography, and all of them were chemically homogeneous substances. Gas chromatographic analysis The results showed that: OPS Ⅰ mainly consists of rhamnose, glucose and galactose; OPS Ⅱ mainly consists of fucose, xylose and glucose.
