摘　　要：首先从不同型号的大孔树脂中(AB-8、D-301、X-5、D-140、S-8和D-101)筛选出大黄鲜磨浆中总蒽醌苷静态吸附率和脱附率较高的X-5型树脂,然后对X-5型大孔树脂的吸附纯化条件进行了优化。实验结果为,X-5型树脂对大黄总蒽醌苷静态吸附率和动态吸附率均最高。X-5型树脂对大黄总蒽醌苷最适宜交换吸附条件为:p H值=9,流速为1 m L/min,洗脱剂为70%乙醇溶液。X-5型大孔树脂交换吸附大黄总蒽醌苷的纯化方法可取,具有良好的应用前景。The adsorption capacity of six kinds of macroporous resin （ AB-8, D-301, X-5, D-141, S-8 and D-101 ） are used to compare total anthraquinones of Radix Et Rhizoma Rhei. The results show that the static and dynamic adsorption rate of X-5 resin of rhubarb anthraquinone is higher than others. The ap- propriate exchange adsorption conditions for X-5 resin are as follow： pH = 9 ; flow rate of 1 mL/min ; the ethanol concentration of 70%. The macroporous resin exchange adsorption purification of rhubarb anthra- quinone with X-5 always works the best and has a good application prospect.
