    Abstract:
    Objective To apply the high performance liquid chromatography (HPLC) method to the determination of four ingredients including paeoniflorin, berberine, evodiamine, and rutaecarpin in Wuji Pellet. Methods Using Thermo-ODS2-Hypersil column (250 mm × 4.6 mm, 5 μm) and taking acetonitrile-0.05 mol/L monopotassium phosphate as mobile phase for elution, the conditions were as follows, flow rate of 1.0 mL/min, UV detector wavelength of 225 nm, and column temperature of 25 ℃. Results The standard curves of paeoniflorin, berberine, evodiamine, and rutaecarpine showed a good linear relationship in 0.0124—0.124, 0.0349—0.349 mg/mL, and 0.6—6, 0.5—5 μg/mL. The average recovery rates were 99.45%, 97.69%, 98.18%, and 98.46%, respectively. Conclusion The method is of high sensitivity and nice reproducibility, and it could be used for the simultaneous determination of the four ingredients in Wuji Pellet.
