Oxidation mechanism of flavanone taxifolin. Electrochemical and spectroelectrochemical investigation
Original language description
The oxidation of taxifolin on glassy carbon electrode in acetonitrile was studied by cyclic voltammetry, UV-vis and IR spectroelectrochemistry. The oxidation products were identified using HPLC-ESI-MS/MS. The two-electron oxidation mechanism differs from that of flavonols (e.g. quercetin) due to the absence of the double bond between atoms C-2 and C-3. As confirmed by IR spectroelectrochemistry, quinone at ring B is formed as low stable intermediate. The oxidation pathway leads to the formation of hydroxylated derivative of taxifolin 2,3,3,4,5,7-hexahydroxyflavone accompanied by the 2,3-desaturation.
