摘　　要：为优选防风粗多糖的脱色材料,以总糖保留率以及脱色率为考察指标,研究了8种不同的树脂对防风粗多糖脱色的效果。仅从脱色率考查,脱色效果依次为D280>D392>201×4>D3520>201×7>NKA-Ⅱ>NKA-9>001×7。对脱色效果较好的2种树脂柱容量的对比结果表明,D280对防风粗多糖的脱色效果优于D392。它们的最佳上样量均为0.04 g/g(湿树脂),二者的脱色率分别为84.3%和76.4%,而总糖保留率分别为80.6%和82.7%。防风粗多糖的脱色宜选用大孔阴离子交换树脂。To select a suitable decolorizing resin for crude Saposhnikovia divaricata polysaccharide （ SPS）, with both the decolorization ratio and the carbohydrate reservation ratio as the indexes, the decolorization effect of crude SPS by eight different resins were studied. The results show that the order of their decolorization ratios is：D280 〉 D392 〉201×4 〉 D3520 〉201 ×7 〉 NKA- Ⅱ 〉 NKA-9 〉001×7, and the column capacity of D280 is higher than that of D392. At their optimal loading, which is 1.2 g crude SPS per 30 g wet resin, the decolorization ratios and carbohydrate reservation ratios are 84.3%, 76.4% and 80. 6%, 82. 7%, respectively. The above results show that macroporous anion exchange resins are suitable for the decolorization of crude SPS.
