摘要
淫羊藿粗多糖经DEAE-52和葡聚糖凝胶柱层析分离纯化得到组分EPSⅠa,通过红外光谱分析发现具有多糖的典型结构;通过HPLC分析发现,EPSⅠa是由鼠李糖、果糖、葡萄糖和2个不确定的单糖组分组成的杂多糖。
EPS Ⅰa was obtained by purifying from the crude polysaccharide through DEAE-52 column chromatography and Sephadex column chromatography respectively. The result by IR analysis indicated that the EPS Ⅰa had the polysaccharide characteristic absorption peak. The result by HPLC analysis indicated that the EPS Ⅰa is composed by rhamnose, fructose, glucose and two uncertainty fragments.
