A screening method using LC-DAD-ESI/MS was applied to the analysis of flavonoids in celery, Chinesecelery, and celery seeds (Apium graveolens L. and varieties). Fifteen flavonoid glycosides weredetected in the three celery materials. They were identified as luteolin 7-O-apiosylglucoside, luteolin7-O-glucoside, apigenin 7-O-apiosylglucoside, chrysoeriol 7-O-apiosylglucoside, chrysoeriol 7-O-glucoside, and more than 10 malonyl derivatives of these glycosides. The identification of the malonylderivatives was confirmed by their conversion into glycosides upon heating and by comparison ofsome of the malonates with malonates that had previously been identified in red bell pepper andparsley. The concentrations of the glycosides and the malonyl glycosides in the three materials wereestimated by comparison to aglycone standards. This is the first report of the presence of theseglycosylated flavonoid malonates in celery.
