Abstract: A method for the determination of paeoniflorin content in Yiganfuzhengqingdu Granules by HPLC was established. HPLC analysis was carried out with Agilent ZORBAX SB-C18 chromatographic column (4.6 mm×250 mm,5 μm) and methanol-0.05 mol/L potassium dihydrogen phosphate(38:62, V/V) as mobile phase, the flow rate was 1.0 mL/min, and the column temperature was 25 ℃,injection volume was 10 μL, the detection wavelength was 230 nm. The results showed that the calibration curve was linear in the range of 0.079 1~0.988 0 μg for paeoniflorin (r=0.999 9), the recovery rate was 98.1%~100.6% with RSD 1.02%(n=6). This method is highly specific, sensitive, reproducible and simple, which can be used for quality control of Yiganfuzhengqingdu Granules.

Key words: Yiganfuzhengqingdu Granules, paeoniflorin, HPLC, content determination
