Abstract
Objective To determine the content of paeonol in Banlonggushen Capsule. Method Sino Chirom C18 column, mobile phase was methanol-0.25% acetic acid (45 ∶ 55). The detection wavelength was at 274 nm and the flow rate was 1.0 mL/min. Result The linearity was obtained in the range of 0.0532~0.3192 μg (r =0.9999). The average recovery was 100.2%. Conclusion The method was simple and reliable. It is suitable for the determination of paeonol in Banlonggushen Capsule.
