A mass spectrometric method based on the combined use of fast atom bombardment collisionally‐induced dissociation (CID) and tandem mass spectrometry has been used for the structural characterization of free and conjugated flavone and flavonol aglycones. Low‐energy CID spectra of the [M + H] + (or Y + 0 ) ions show simple fragmentation patterns, which allow characterization of the substituents in the A and B rings and, in particular, differentiation between flavones and flavonols. A systematic nomenclature for product ions produced from protonated molecules under CID conditions is proposed. © 1997 John Wiley & Sons, Ltd.
