Artemisia argyi Lévi. et Vant is a traditional Chinese medicine with a long history, and its buds and seedlings can be used as vegetables. However, the investigations on the chemical constituents of A. argyi are not sufficient. In this paper, ultra-high performance liquid chromatography tandem hybrid quadrupole-orbitrap mass spectrometry (UPLC-Q-Exactive-MS/MS) was used to identify the chemical constituents of A. argyi. The Q Exactive mass spectrometer was used to collect MS and MS² data. Finally, 125 compounds were preliminarily identified in A. argyi by comparing the retention time and accurate molecular weight with standard databases such as MZVault, MZCloud, and BGI Library (self-built standard Library by BGI Co., Ltd), including flavonoids, phenylpropanoids, terpenoids, and organic acids.
