摘要
目的建立HPLC-ELSD同时测定小儿宝泰康颗粒中2个指标成分贝母素甲、贝母素乙含量的方法。方法采用Thermo C18(250mm×4.6mm,5μm)色谱柱,流动相:乙腈-水-二乙胺(65∶35∶0.03),流速:1.0ml/min;ELSD参数为漂移管温度:85℃,载气流速:2.2L/min。结果贝母素甲在0.586~5.860μg(r=0.999 6)、贝母素乙在0.564~5.640μg(r=0.999 9)与峰面积的对数值呈线性关系;平均加样回收率分别为99.44%和98.56%,RSD分别为0.7%和1.0%。结论该方法简便、准确、重复性好,可用于小儿宝泰康颗粒的质量控制。
Objective To develop a new high performance liquid chromatography(HPLC)coupled with Evaporative Light Scattering Detector(ELSD)method for simultaneous determination of two indicative components(peimine and peiminine)in Xiaoer Baotaikang granules.Methods The analysis was performed on a Thermo C18column(250 mm × 4.6 mm,5μm)by using a mobile phase consisted of acetonitrile-water and diethylamine(65∶35∶0.03),and the flow rate was1.0ml/min;ELSD parameters:the temperature of drift tube was 85℃and the carrier gas flow rate was 2.2L/min.ResultsThe linear ranges of peimine and peiminine were 0.586~5.860μg(r=0.999 6)and 0.564~5.640μg(r=0.999 9),respectively.The average recovery rate for peimine and peiminine was 99.44%(RSD was 0.7%)and 98.56%(RSD was 1.0%),respectively.Conclusions The method is sample,accurate and reproducible,which could be used for the quality control of Xiaoer Baotaikang granules.
