摘要
从南沙参根提取得到粗多糖,经DEAE-纤维素和葡聚糖凝胶Sephadex G-200柱层析得到两个均一的多糖成分(AP-1、AP-3),平均分子量AP-1为8.3万,AP-3为6.3万。糖组成分析表明:AP-1为一葡聚糖,AP-3是含有葡萄糖、鼠李糖、阿拉伯糖、葡萄糖醛酸(5:1:1:3)的杂多糖。
Polysaccharides,AP-1 and AP-3,were obtained through extraction of the roots of Adenophora potaninii Korsh by hot water,followed by the isolation and purification by DEAE-cellulose and Sephadex G-200 column chromatography. It was proved to be homogeneous by gel filtration chromatography and their average MW was estimated to be 8.3×104 and 6.3×104 respectively. Analysis of sugar composition showed that AP-1 is D-glucan,while AP-3 is composed of glucose,rhamnose,arabinose and glucronic acid in the molar ratio of 5:1:1:3.
