摘    要:目的:对仿刺参肠道多糖进行纯化,并对纯化产物进行理化分析。方法:使用葡聚糖凝胶(G-100)层析柱分离出两种仿刺参肠道多糖,选取其中多糖A进行研究。使用葡聚糖凝胶(G-100)柱层析法和琼脂糖凝胶电泳法进行纯度检测,葡聚糖凝胶(G-200)柱层析测定分子质量,高效液相色谱法确定其单糖组分,并结合红外吸收光谱法与核磁共振对其结构进行初步检测。结果:实验所得纯化产物多糖A为均一组分,主要含有氨基糖醛酸、氨基半乳糖盐酸盐和岩藻糖3种单糖,并含有少量的氨基葡萄糖、半乳糖。其中岩藻糖有α和β两种构型,以α-岩藻糖硫酸酯残基、β-岩藻糖硫酸酯残基形式存在。分子质量约为18.8×104D。结论:该纯化产物多糖A为一种酸性多糖,推测其为硫酸软骨素类。

关 键 词:肠道多糖  纯化  单糖分析  结构鉴定  海参  仿刺参

Abstract:Objective: To purify and physicochemically analyze polysaccharides from the intestinal tract of Apostichopus japonicus.Methods: Two polysaccharides,named as polysaccharides A and B,respectively,were isolated and purified by using SephadexG-100 column from the intestinal tract of Apostichopus japonicus,and polysaccharide A was selected to study its physicochemical properties.Its purity was evaluated by SephadexG-100 column chromatography and agarose gel electrophoresis.The relative molecular mass was determi...
Keywords:intestinal tract polysaccharide  purification  component analysis  structure identification  Apostichopus japonicus
