Determination of paeoniflorin in Chinese traditional herbal preparation Fuzhengpingxiao capsule using HPLC method
Abstract:Objective To determine the content of paeoniflorin in Fuzhengpingxiao capsule by HPLC method. Methods The content of paeoniflorin were determined by HPLC, and the column was an Agilent Zorbax SB-C18 column (150 mm×4.6 mm, 5 μm); The mobile phase was acetonitrile and 5 mmol/L sodium dihydrogen phosphate (10:90), and the flow rate was set at 1 ml/min. Column temperature was 25℃, detection wavelength was 230 nm, injection volume was 10 μl, and running time was 25 min. Results Paeoniflorin was linear (r=0.999 9) in the concentration of 25.0-500.0 μg/ml, the linear equation was Y=12.65X +43.54, and the average recovery was 92.69% with RSD value was 1.77%. Conclusion The method was easy to operate, reliable and reproducible, which could be used in the determination of paeoniflorin in FuzhengPingxiao capsule.
