ABSTRACT
OBJECTIVE: To establish a method for simultaneous determination of nine components in Huoxiang zhengqi oral liquid, and to improve and perfect the quality standard of Huoxiang zhengqi oral liquid. METHODS: The contents of nine components in 10 batches of Huoxiang zhengqi oral liquid were determined by HPLC, such as licorice coumarin, isorlicin, liquiritinapioside, narirutin, liquiritin, saponinshesperidin, magnolol and honokiol. The determination was performed on Kromasil Eternity XT-5-C18 column with mobile phase consisted of acetonitrile-0.05% phosphoric acid solution (gradient elution) at the flow rate of 1 mL/min. The detection wavelength was set at 220 nm, and column temperature was 25 ℃. The sample size was 10 μL. RESULTS: The linear range of licorice coumarin, isorlicin, liquiritinapioside, narirutin, liquiritin, saponinshesperidin, magnolol and honokiolin were 0.000 5-0.007 5, 0.000 8-0.025 0, 0.006 1-0.976 0, 0.001 6-0.250 0, 0.007 8-0.025 0, 0.000 4- 0.062 7, 0.008 6-0.276 0, 0.010 0-0.500 0, 0.010 0-0.500 0 mg/mL (r=0.999 2-1.000 0). The detection limits were 0.001 3, 0.000 1, 0.004 7, 0.005 0, 0.012 0, 0.001 3, 0.007 8, 0.007 7 0, 0.005 8 μg/mL, and the quantitative limits were 0.013 0, 0.000 8, 0.047 0, 0.050 0, 0.120 0, 0.013 0, 0.078 0, 0.070 0, 0.058 0 μg/mL, respectively; RSD of precision, stability and repeatability tests were less than 3.0% (n=6). Average recovery rates were 98.67%, 101.85%, 98.97%, 103.05%, 100.00%, 97.78%, 97.91%, 100.13%, 101.95%; RSDs were 1.14%, 2.18%, 0.40%, 0.17%, 1.38%, 0.85%, 1.38%, 0.10%, 1.35% (n=6). CONCLUSIONS: The established method is accurate and reliable, which can provide reference for the establishment of the overall quality control evaluation system and the improvement of quality standard for Huoxiang zhengqi oral liquid.
