Problems solved by technology

[0002] The chemical composition of traditional Chinese medicine and its compound is complex, the sources of medicinal materials are different, and the content of main components varies greatly, which may easily lead to unstable quality of finished medicine and affect the efficacy of medicine. According to the traditional analysis method, the detected ingredients are single or few, and it takes a long time. The detection cycle, more manpower and material resources, and high detection cost cannot meet the needs of different traditional Chinese medicine compounds

Abstract

The invention provides a method for determining chemical components in traditional Chinese medicines by liquid chromatography-mass spectrometry. The method comprises the steps of preparing a mixed standard solution and a tested traditional Chinese medicine solution, and carrying out sample injection determination by using a liquid chromatography and mass spectrometry combined technology; and by comparing an accurate molecular weight, retention time with the chemical components in the mixed standard solution, carrying out qualitative and quantitative determination on the corresponding chemicalcomponents in a traditional Chinese medicine extracting solution. The invention further provides application of the method, and it can determine that the traditional Chinese medicines comprise the following chemical components: one or more of benzoylaconitine, benzoylmesaconine, atractylodes macrocephala lactone I, atractylodes macrocephala lactone II, atractylodes macrocephala lactone III, codonopsis alkynyl glycoside, liquiritin, liquiritigenin, 8-gingerol and 10-gingerol. By the method, simultaneous detection and quantification of one or more of the 10 chemical components in the traditionalChinese medicines can be realized. The method has the advantages of rapid and efficient determination method, high sensitivity and simple and feasible determination method, and a methodological basisis provided for the quality control of the traditional Chinese medicines.
