The invention provides a method for detecting a pharmaceutical composition. The pharmaceutical composition is a composition containing hypericum perforatum extract, which is detected by liquid chromatography. The detection conditions of the liquid chromatography are as follows: chromatographic column: octadecylsilane bonded silica gel as filler; mobile phase A is acetonitrile, mobile phase B is 0.1% phosphoric acid solution, the detection wavelength is 360nm, and gradient elution is adopted. The method has the advantages of rapidity, high efficiency, stability, accuracy and the like, and can quickly and effectively detect the pharmaceutical composition. |
