Abstract:

Syzygium myrsinifolium (Hance) Merr. et Perry is a unique plant resource on Hainan Island, and there are few reports on its chemical constituents. In the present study, we identified the major chemical constituents in the leaves of Syzygium myrsinifolium (Hance) Merr. et Perry using ultra-high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS/MS). The chemical constituents in Syzygium myrsinifolium (Hance) Merr. et Perry were identified rapidly based on the accurate relative molecular mass and combined with literature data and reference substances. A total of 20 compounds, including organic acids, phenolic acids, and flavonoids, were identified. Among these 20 compounds, four organic acids, eight phenolic acids, seven flavonoids, and one coumarin were reported from the leaves of Syzygium myrsinifolium (Hance) Merr. et Perry for the first time. The established method was rapid and accurate, and some chemical constituents in the leaves of Syzygium myrsinifolium (Hance) Merr. et Perry have been identified. This research provided an experimental reference for the study of the constituents and utilization of Syzygium myrsinifolium (Hance) Merr. et Perry.

Key words: Syzygium myrsinifolium (Hance) Merr. et Perry, UPLC-Q-TOF-MS/MS, Identification
