The effects of sample concentration and ionic strength of mobile phase on retention time were studied. The mechanism for the effects on Mw determination results of polysaccharides by HPGPC was also discussed.展开更多
本研究用DEAE-sepharose Fast Flow柱从百合水提物中分离纯化得到两种多糖LLP1、LLP2,经高效凝胶渗透色谱法(HPGPC)鉴定LLP1为单一组分、LLP2为糖蛋白,将这两种多糖进行气相色谱分析。结果如下:LLP1由甘露糖、葡萄糖和阿拉伯糖组成,分...本研究用DEAE-sepharose Fast Flow柱从百合水提物中分离纯化得到两种多糖LLP1、LLP2,经高效凝胶渗透色谱法(HPGPC)鉴定LLP1为单一组分、LLP2为糖蛋白,将这两种多糖进行气相色谱分析。结果如下:LLP1由甘露糖、葡萄糖和阿拉伯糖组成,分子量为11756D,LLP2由半乳糖、鼠李糖和阿拉伯糖组成,分子量1038773D。展开更多
