Abstract: BACKGROUND: Heilongjiang Province is a frontier province with distinctive characteristics, fertile land and rich products. OBJECTIVE: This study provides a new method for qualitatively studying flavonoids in traditional Chinese medicine and a new auxiliary means for identifying flavonoid isomers. METHODS: The flavonoids in Polygala fallax Hemsl were identified by ultra-performance liquid chromatography-photo-diode array (PDA)-quadrupole-electro- static field orbitrap mass spectrometry tandem by UV Spectrum, primary and secondary high-resolution mass spectrometry (MS 1 /MS 2 ) cleavage of fragments combined with databases, mass spectrometry cleavage patterns and literature.…RESULTS: The established QSRR model was used to verify the flavonoids identified from the Polygala fallax Hemsl. CONCLUSION: The structure of multiple Polygala fallax Hemsl has been identified using various spectral methods. The tumor cytotoxic activity of the isolated compounds was evaluated. This paper is of great significance for further elucidating the pharmacodynamic substance basis and further developing and utilizing Polygala fallax Hemsl.
