To clarify the chemical components of the Qiang medicine Primula chungensis Balf.f.et Ward.,ultra performance liquid chromatography-quadrupole/orbitraphigh resolution mass spectrometry (UPLC-Q-Exactive-Orbitrap-MS) was analyzed in this work.Electron spray ionization (ESI) source was adopted with both positive and negative ions.The chemical components were analyzed and identifiedaccording tothe precise mass,fragment ions,retention time combined with the references.A total of ninety-two compounds were identified in the P. chungensis,and the main chemical components included thirty-nine flavonoids,thirteen organic acids,eighteen fatty acids,eight amino acids,four phenylpropanoids,three iridoids and other compounds.Using UPLC-Q-Exactive-Orbitrap-MS technology can provide a fast and accurate method for the identification of chemical constituents in P. chungensis for the first time,which lays a foundation for further research on the pharmacology substance basis and quality control.
