| 摘 要： | 对药桑红色素的纯化工艺进行了研究,比较了AB-8、D-101、氧化铝、聚酰胺(14-30目)、聚酰胺(100-200目)五种吸附剂对药桑红色素的静态吸附-脱附性能,结果表明:AB-8大孔树脂对药桑红色素具有较强的选择性,在相同试验条件下,吸附量大,且易被解吸。在此研究的基础上进行了AB-8大孔树脂分离纯化药桑红色素的最佳工艺研究,比较了原料液浓度,NaCl浓度,原料液pH值,洗脱剂浓度,洗脱剂pH值等对树脂静态吸附-解吸的影响,并在静态试验的基础上,进行了动态吸附-解吸试验的研究,以确定最佳吸附、解吸流速,结果表明,AB-8大孔树脂对药桑红色素分离纯化最优吸附条件为:原料色素液pH值为2.04,吸光度为0.567,吸附流速1mL/min;最优洗脱条件为:洗脱剂(乙醇)浓度95%,pH值为1,洗脱流速0.8mL/min。此工艺条件能够较好地分离纯化药桑红色素。
