Application of liquid chromatography-mass spectrometry technology in the detection of pyrrolizidine alkaloids in agricultural products

Pyrrolizidine alkaloids (PAs) are natural toxins with multiple toxicities such as hepatotoxicity, genotoxicity and carcinogenicity to the human body. As a new risk factor in agricultural products, pyrrolizidine alkaloids have been widely concerned. Efficient and sensitive detection technology is an important means for effective supervision of PAs in agricultural products. Liquid chromatography-tandem mass spectrometry is the most widely used detection technology in the study of PAs in agricultural products. In this paper, PAs and liquid chromatography-tandem mass spectrometry (LC-MS) were briefly introduced, and the application of LC-MS in the detection of PAs in agricultural products was briefly analyzed, and its application prospect was prospected, in order to provide reference for the supervision of PAs.
