Objective:To improve the quality standard of Pishen Liangzhu pills
the study of HPLC methodology was carried out to determine the paeoniflorin in the pills. Method: Using HPLC. The separation was performed on Kromasil-C18 column(4.6 mm×250 mm
5 μm)
using a mixture of acetonitrile-0.05 mol·L-1 potassium dihydrogen phosphate (10∶90) as the mobile phase; the detection wavelength was wet at 230 nm. Result: The calibration curve was linear within the range of 0.106 2-1.062 μg (r=0.999 95). The average recovery for paeoniflorin was 96.83%. Conclusion: The method is selective
accurate and simple. It is suitable for controlling the quality of Pishen Liangzhu pills.
