ABSTRACT Objective: A method was established for determination the content of Ferullic acid in Dangguibuxue Granules by HPLC.Method: Lichrospher C18column(200 mm×4.6 mm,5 μm)was used. The mobile phase consisted of acetonitrilewaterglacial acetic acid(18∶82∶2).The detection wavelength was at 320 nm.Result: The calibration curve was in good linearity within the range of0.021-0.315μg(r=0.999 9), the average recovery was 100.29%(RSD=2.09).Conclusion: The method is simple and rapid. It can be used to determine the Ferullic acid in this preparation.
