The seperation was performed on a ACQUITY UPLC BEH C18 column (2.1 mm×100 mm, 1.7μm). The mobile phase was composed of acetonitrile and 0.1% formic acid with gradient elution. The flow rate was 0.4 mL·min-1 and the temperature was 35℃.The detection wavelength at 280nm. The method validation proved that the linearity, precision, repeatability, stability and recovery accorded with the requirement for anassay. The established method had been used for determination above eight components in three lots of Jinxin Oral Liquid, and the results showed that this method was simple, accurate and very suitable to the quality control of Jinxin Oral Liquid.
