ABSTRACT Objective:To develop a method for the determination of paeoniflorin in Gujing Pills by RP-HPLC。Method:The ZORBAX SB-C18 column(250 mm×4.6mm,5 μm)was used。 The mobile phase consisted of methanol-0.05mol·L-1 potassium dihydrogen phosphate solution triethylamine(28:72:0.5);the detection wavelength was at 230 nm. The flow rate was 1.0ml·min-1。The column temperature was 40 ℃。Result:A good linear relationship was in the range of 0.44-3.96μg (r=0.999 9),the average recovery was 99.2%,RSD1.2%(n=5)。Conclusion: This method is accurate,sensible and reproducible。
