The oxidation mechanism of the antioxidant quercetin in nonaqueous media

Original language description

The knowledge of the degradation pathways of natural dyes used in medieval textiles is necessary for the restoration of their original color. Quercetin, one of such colorants, reportedly yields the wide spectrum of oxidation products in different types of media. This study deals with electrochemical oxidation mechanism of quercetin in nonaqueous solution, which has not been yet attempted. The final oxidation product at the first oxidation wave was identified by HPLC-DAD and GC?MS techniques as 2-(3,4-dihydroxybenzoyl)-2,4,6-trihydroxybenzofuran-3(2H)-one. The apparent two-electron process at the potential of the first oxidation wave yields current?voltage shapes with one-electron characteristics. The in situ spectroelectrochemistry measurements provedthe oxidation mechanism leading through a short-lived anion radical.
