Objective:To optimize the purification technology of Chaiqin Qinggan formula extract by macro-porous resin.Method:The macroporous resin was selected and the purification process was evaluated by measuring the content of baicalin
paeoniflorin
glycyrrhizin and total saponins.Result:The AB-8 macroporous resin was select-ed with 0.75 g.mL-1 the loading concentration of crude drug and 3 BV.h-1 current velocity
70% ethanol as the e-luting reagent with the eluting velocity of 5 BV.h-1.Conclusion:The method is effective for purification of Chaiqin Qinggan formula extract.
