Comparison of flavonoid profiles of Agauria salicifolia (Ericaceae) by liquid chromatography-UV diode array detection-electrospray ionisation mass spectrometry.
Liquid chromatography (LC) coupled to negative electrospray ionisation (ESI) tandem mass spectrometry (MS/MS) was used for the rapid and sensitive identification of flavonoid compounds in Agauria salicifolia. The leaf flavonoid content in individual of A. salicifolia originating from population with contrasted ecogeographical situation and morphological characteristics was found to be variable qualitatively and highly variable quantitatively. Identification of the compounds was carried out by interpretation of UV, MS and MS/MS spectra. Fourteen flavonoids were identified, all of which had not previously been reported in Agauria spp. Two flavonol-O-glucuronides were found to differentiate the two populations.
