【Abstract】 Objective To establish an HPLC method for the analysis of thirteen main chemical constituents (gallicacid, 5-hydroxymethylfurfural, methylgallate, oxypaeoniflora, catechins, paeoniflorin, 1,2,3,6-tetra-O-galloyl-D-glucose, 1,2,4,6-tetra-O-galloyl-D-glucose, benzoicacid, 1,2,3,4,6-penta-O-galloyl-D-glucose, mudanpioside C, benzoyloxypaeoniflorin, and paeonal) in Moutan Cortex from different origins. Methods The methanol (50%) reflux extraction was adopted to Moutan Cortex. Separation was carried out on C18 (250 mm × 4.6 mm, 5 μm), the mobile phase was eluted with acetonitrile-0.5% phosphoric acid. The flow rate was 1.0 mL/min, the detection wavelength was 254 nm, and the column temperature was 30 °C. Results The linear relation of thirteen main active components measured in the range of mass concentration was good with perfect precision, repeatability, and stability, the value of which was all more than 0.999 5. Conclusion The HPLC method established for simultaneous determination of thirteen main chemical compositions in Moutan Cortex is effective, accurate, and reproducible, which can be used for the quality control of Moutan Cortex.
