RESUMO
Traditional Chinese medicine (TCM) has made numerous contributions to the prosperity of China. However, the phytochemicals of TCM are complex, and there are significant differences in relative content. The material basis of TCM has restricted the modernization of TCM. Liquid chromatography-mass spectrometry (LC-MS) combines the high separation performance of chromatography and the high sensitivity of mass spectrometry. It has been widely used in the analysis of natural medicines and can greatly promote the development of TCM. Many studies have focused on the comprehensive characterization of phytochemicals, building a strategy for the rapid, accurate and systematic analysis of the chemical components of TCM through the integration of different mass spectrometric techniques, and laying the foundation for quality control and rational utilization of TCM.
