Abstract: Objective To establish a method for simultaneous determination of Loganin, Cinnamic aldehyde, Paeoniflorin and Paeonol in Guifu Dihuang Pills (concentrated pills) with HPLC.Methods HPLC was performed on an Agilent Zorbax Extend C18(250 mm×4.6 mm,5 μm) with the column temperature was 30 ℃.Gradient elution was carried out with methanol as the mobile phase A and 0.35% phosphoric acid as the mobile phase B at a flow rate of 1.0 mL·min -1.The detection wavelength was 240 nm and the injection amount was 10 μL. Results Loganin, Cinnamic aldehyde, paeoniflorin and paeonol within the range of 2.09-83.56 μg·mL-1, 2.01-80.24 μg·mL-1, 2.08-83.28 μg·mL-1, 3.03-121.04 μg·mL-1, showing a good linear relationship (r=0.9994、0.9999、0.9998、0.9996), and the average recovery (n=6) was 99.39 %, 98.98 %, 98.99 %, 99.22 %, respectively. The recoveries were 99.60 %, 96.96 %, 99.32 % and 98.86 %(n=6), RSD were 0.72 %, 1.51 %, 0.55 % and 1.47 % respectively.Conclusion This method is simple, accurate and reproducible and can be used as a quality control method for Guifu Dihuang Pills (concentrated pills).
