To analyze the chemical components of the tender leaves of Cyclocarya paliurus, a rapid qualitative analysis of the chemical components of the percolation extracts of the tender leaves of Cyclocarya paliurus was carried out by ultrahigh-performance liquid chromatography coupled with quadrupole-time-of-flight tandem mass spectrometry (UHPLC-Q-TOF-MS/MS). Mass spectrum data were collected in the positive and negative ion modes, and MassHunter qualitative analysis software was used, according to the retention time and mass spectrum information of each compound, combined with existing literature and mass spectrum databases, the compounds were analyzed for the fragmentation rule, 94 compounds were identified from Cyclocarya paliurus, including 29 flavonoids, 16 triterpenes, 25 organic acids, 24 other compounds. The analysis results showed that the percolation extract of Cyclocarya paliurus contained flavonoids, organic acids, triterpenoids, coumarins, amino acids, and other compounds, and malic acid, hesperidin, rosin, 6,7-dihydroxycoumarin, 6-methylcoumarin, 5,7-dimethoxycoumarin are found in Cyclocarya paliurus for the first time. This study can lay a foundation for further clarifying the material basis of Cyclocarya paliurus. It provides a theoretical basis for the development of relevant products of Cyclocarya paliurus.
