The oxidation of luteolin, the natural flavonoid dye
Original language description
The oxidation of natural flavonoid luteolin in aqueous solution is studied by electrochemical methods, electron paramagnetic resonance (EPR), spectroelectrochemistry and separation techniques HPLC-DAD and HPLC?MS/MS. The number of electrons involved in the oxidation of luteolin depends on the presence of its dissociation forms in solution. The study explains the differences in the number of electrons presented in the literature. The overall one electron oxidation mechanism of luteolin in alkaline solution is explained by the comproportionation reaction of resulting quinone, despite the fact that quinone is formed by two electron oxidation. Then a hydroxylation takes place. The EPR spectroelectrochemical study of the semiquinone radical anion formationas well as of the reaction steps following the electron transfer during the oxidation is presented. The novelty of this contribution consists in the additional temperature controlled semi-quantitative in situ EPR spectroelectrochemical ex
