In 2020, the state will implement a comprehensive reduction and ban of animal husbandry antibiotics. Finding substitute for antibiotics is of great importance to the sustainable and stable development of animal husbandry. Plant extract has become the focus of research due to its antibacterial and antioxidant effects. Accurate determination of plant extract content is very important. Liquid chromatography tandem quadrupole-mass spectrometry (LC-MS) has been applied to many industries in recent years as a frontier separation, analysis and detection technology. This paper reviewed the research on the determination of plant extract content by LC-MS in recent years, in order to provide technical and theoretical support for the application of plant extract as a substitute antibacterial substance in animal husbandry and the determination of its usage and dosage, and also to provide reference for the establishment of the determination standard of plant extract content.
