It was assumed that gas-phase ligation of metal monocations by flavonoids might provide some insight on the intrinsic antioxidant activity of the latter. Thus, the ligation of Fe+ and Cu+ ions by apigenin (1), luteolin (2), kaempferol (3), quercetin

The hydrogen and carbon randomization in the mass spectrometric behaviour of benzophenone has been studied by deuterium and 13C-labelling. Hydrogen scrambling is involved only in the reactions of primary loss of hydrogen from molecular ions, as well
