. They were analyzed by ultra high performance liquid chromatography(UHPLC). Waters HSS T3 chro
matographic column(100 mm×2.1 mm,1.8 μm) was used. The mobile phase was consisted of 0.05% phosphoric acid solution and acetonitrile. The elution mode was gradient elution. The detection wavelength was set at 215 nm and 254 nm by diode-array detector(DAD). There were 22 common peaks in the fingerprints. The ultra high performance liquid chromatography quadrupole time of flight mass spectrometry(UHPLC-Q-TOF MS) was used to infer the structure of the compounds in the common peaks. The relative standard deviations(RSDs) of precision,repeatability and stability were all less than 6.0%. The linear relationship of 10 components was good within the quantitative range. The determination coefficients(

) were higher than 0.999. RSDs of injection precision and method repeatability were less than 6.0%. The sample solution was stable within 24 hours,and the recoveries of each component were 91.9%-104%. 12 batches of Xiaochaihu Capsules from different batches were analyzed using the established analytical method. The results showed good consistence of Xiaochaihu Capsules among different batches. The established analytical method is stable,accurate and reliable. It can be used to detect the index components in Xiaochaihu Capsules. The detection results can reflect the quality of Xiaochaihu Capsules more comprehensively.
