Abstract
Objective: To establish a method of HPLC for quantitative determination of paeonol and paeoniflorin in the extraction of Danshao Formula. Method: The separation was performed on the chromatographic column of ODS HYPERSIL (4.6 mm×250 mm
5 μm)
and the mobile phase in the gradient elution program was acetonitrile-water. The column temperature was maintained at 32℃. The flow rate was 0.8 mL·min-1
and the detection wavelength was set at 274 nm and 230 nm respectively. Result: Paeonol and paeoniflorin showed good linear relationship in the range of 0-0.202 1
0-27.960 0 μg. The average recovery was 97.40% (RSD 1.18%)
101.35% (RSD 0.48%) respectively. Conclusion: The method is easy and accurate with higher repeatability
which can be used in the quality control of paeonol and paeoniflorin in the extraction of Danshao formula.
