Ixeris sonchifolia injection fingerprint spectrum examination method

The invention discloses a traditional Chinese medicine injection fingerprint spectrum examination method, namely an ixeris sonchifolia injection fingerprint spectrum examination method. By investigating methods such as chromatographic conditions, system suitability, a preparation method of a reference solution, a preparation method of a test solution and a sample size, the best detection method is established; and by investigating precision, stability and repeatability, the fact that the method meets various requirements of a fingerprint spectrum analysis method can be proved. The established ixeris sonchifolia injection fingerprint spectrum analysis method can sensitively and accurately carry out quality control on ixeris sonchifolia injection, the defect that the ixeris sonchifolia injection quality standard lacks a fingerprint spectrum examination item can be made up, and a corresponding technical method is provided for safety revaluation of the ixeris sonchifolia injection. 本发明公开了种中药注射液指纹图谱检查方法，即苦碟子注射液指纹图
