Abstracts
The present paper reports electrochemical and UV-VIS spectroscopic studies on the process of electrooxidation of quercetin 3,4'-di-O-β-glucopyranoside (Q 3,4'-diglc) molecule, at glassy carbon electrode
surface in 0.1 M sodium acetate – acetic acid buffer in 90 % methanol solution. The process starts at 3'-OH group (ring B), followed by oxidation of 5,7-dihydroxyl group in ring A. As a result of electrochemical reactions, the surface area of glassy carbon (GC) electrode becomes extensively blocked by Q 3,4'-diglc oxidation products.

Keywords
Q 3; 4'-diglc electrooxidation; cyclic voltammetry; impedance spectroscopy; UV-VIS spectroscopy
