Abstract: Objective To optimize the extraction methods and develop a HPLC-DAD assay for the determination of three effective ingredients in Moutan Coretex. Methods The analysis was performed on an Agilent ZORBAX Eclipse Plus (4.6 mm×150 mm, 5 μm) column with acetonitrile and water (0.6% formic acid) as mobile phase at a rate of 1.0 ml/min, the detection wavelength was 254 nm, the injection volume was 10 μl. Results The regress equation of gallic acid, paeoniflorin and paeonol were Y=16.598 0X+4.950 2, r=0.999 9; Y=1.613 1X+0.995 1, r=0.999 9; Y=5.981 7X+54.103 0, r=0.999 7, respectively. The average recoveries were 100.7%, 99.2%, 97.8% and RSD(n=9) were 1.6%, 3.0%, 1.1%. Conclusion The extraction effect was good and the determination assay was reliable and accurate.
