摘要
目的: 用胶束动电毛细管色谱法测定维C银翘片中扑热息痛、扑尔敏、氯原酸和维生素C 的含量。考察了不同条件下的电泳行为。方法: 以含40 m mol·L- 1 脱氧胆酸钠的20 m mol·L- 1 硼砂溶液(pH9-11) 为运行缓冲液, 毛细管有效长度为55 cm (ID75 μm) , 以肉桂酸为内标, 于254 nm 波长处测定。结果: 扑热息痛、扑尔敏、氯原酸和维生素C 的加样回收率分别为99-6 % , 99-9% , 99-3% , 99-7 % ; RSD 分别为1-0 % , 1-4% ,1-7 % , 1-8 % 。结论: 本方法操作简便、快速、准确。
Objective:A micellar electrokinetic capillary chromatographic(MECC) method for the simultaneous determination of four active constituents (chlorogenic acid,acetaminophen,chlorphenamine maleate and vitamin C) in V C Yinqiao tablets was developed.Method:The running buffer solution was 20 mmol·L -1 sodium borate buffer(pH 9 11) added 40 mmol·L -1 SDC.The internal standard was cinnamic acid.The capillary column efficient length was 55 cm(ID 75 μm).Results:The recoveries of acetaminophen,chlorphenamine maleate,chlorogenic acid and vitamin C were 99 6%,99 9%,99 3% and 99 7%,respectively.Conclusion:This method is convenient,rapid and accurate.
