Abstract: 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 C18 column (250 mm×4.6 mm, 5 μm) by using a mobile phase consisted of acetonitrile-water and diethylamine(65:35:0.03), and the flow rate was 1.0 ml/min; ELSD parameters:the temperature of drift tube was 85℃ and the carrier gas flow rate was 2.2 L/min. Results The linear ranges of peimine and peiminine were 0.586~5.860 μg (r=0.9996) and 0.564~5.640 μg (r=0.9999), respectively. The average recovery rate for peimine and peiminine was 99.44% (RSD was 0.7%) and 98.56% (RSD was 1.0%),respectively. Conclusion s The method is sample,accurate and reproducible, which could be used for the quality control of Xiaoer Baotaikang granules.
