    Abstract:
    OBJECTIVE: To develop a UPLC method for the simultaneous determination of liquiritin, narirutin, hesperidin, ammonium glycyrrhetate, honokiol and magnolol in Huoxiang Zhengqi oral liquid. METHOD: A Zorbax Eclipse C18 column was used with the mobile phase of acetonitrile and 0. 05% phosphate acid by gradient elution at the detection wavelength of 220 nm. The flow rate was 0.42 mL x min(-1) and the column temperature was 30 degrees C. RESULT: The calibration curves were linear in the ranges of 0.001 7-0.034, 0.003 4-0.068, 0.006 4-0.128, 0.012 8-0.256, 0.003 2-0.064, 0.006 4-0.128 microg, respectively. The average recoveries were 103.3%, 98.39%, 98.29%, 102.1%, 98.45%, 102.2% with RSDs of 2.1%,1.0%, 0.50%, 2.3%, 0.9%, 2.0%, respectively. CONCLUSION: The UPLC method was simple, rapid and accurate, it could be used for quality control of Huoxiang Zhengqi oral liquid.
