Abstract:

In order to systematically investigate the chemical constituents of Citri Reticulatae Folium (leaves of ‘Fuju’), an analytical method that included high-performance liquid chromatography, diode array detection, electrospray ionization, and ion-trap time-of-flight mass spectrometry (HPLC-DAD-ESI-MSn) was used to separate and identify the individual chemical components of Citri Reticulatae Folium. As a result, 96 compounds were tentatively identified in this study: including 31 phenolic acids, 4 flavonoid aglycones, 6 flavonoid mono-O-glycosides, 10 flavonoid-O-diglycosides, 5 flavonoid mono-C-glycosides, 5 flavonoid di-C-glycosides, 6 flavonoid O,C-glycosides, 5 (3-hydroxy-3-methylglutaryl) glycosyl flavonoids, 1 flavan-3-ol,and 2 alkaloids. In addition, 21 polymethoxy flavonoids (PMFs) were identified in this paper. Among these compounds, 52 compounds, which were previouslyfound in other Citrus plants, have been identified for the first time in Citri Reticulatae Folium. 15 compounds have not been previously found in theCitrusgenus were identified. Moreover, 9 potentially new compounds have also been detected in this paper. This is the first report of the full characterization of chemical components of Citri Reticulatae Folium (leaves of ‘Fuju’) by HPLC-DAD-ESI-MSn.

Key words: Citri Reticulatae Folium (leaves of ‘Fuju’), HPLC-DAD-ESI-MSn, Flavonoid, O,C-Glycosides, PMFs
