Objective To establish a quantitative method for simultaneous determination of ferulic acid and paeoniflorin in Jiegu Tablets by HPLC. Methods The separation was performed on an Agilent Zorbax SB C18 column (250 mm × 4.6 mm, 5 μm). The mobile phase consisted of acetonitrile and 0.1% phosphoric acid solution (12∶88), at the flow rate of 1.0 mL/min. The detection wavelength was 230 nm. The column temperature was 30 ℃. The injection volume was 10 μL. Results The total running time was 20 min. The linear relationship between the concentration and peak areas of the two compounds were all linear (r >0.999 9). The precision, recovery, and repeatability tests met the demands for quantitative determination well. Conclusion The method could be used for the quality control of Jiegu Tablets with a good sensitivity, accuracy, and reproducibility.
