The invention discloses a method for detecting nine chemical components in traditional Chinese veterinary medicine mysorethorn, and belongs to the technical field of detection methods. The detection method disclosed by the invention is carried out by adopting high performance liquid chromatography, and the high performance liquid chromatography determination conditions are as follows: a chromatographic column takes octadecylsilane chemically bonded silica as a filler and takes a mixed solvent of an organic phase and a water phase as a mobile phase; wherein the water phase is a phosphate buffer solution and serves as a mobile phase A, an organic phase in the mobile phase is acetonitrile and serves as a mobile phase B, and gradient elution is adopted. The detection method provided by the invention is used for detecting the nine chemical components in the traditional Chinese veterinary medicine mysorethorn, has good separation degree with other components in mysorethorn, is stable in base ...
