Abstract: Objective To provide a better reference for the quality control of Nujin Pian by establishing the method for the determination of paeonol in Nujin Pian by HPLC. Methods HPLC was used Agilent XDB C18 column (4.6 mm×150 mm, 4.6 μm), mobile phase was composed of methanol-water (45∶55). The flow rate was 1.0 mL/min with detection wavelength at 274 nm and column temperature at 40 ℃. Results The regression equation of paeonol was Y=7×107X-16 965, r 2=0.999 8 (n=6). The linear range of paeonol was 0.003 8-0.38 μg. The average recovery rate was 99.7%, and RSD was 1.56% (n=6). Conclusion The method is simple, fast and accurate with good reproducibility. It can provide reference for the quality control of Nujin Pian.
