Abstract: This study is focused on investigation of oxidation pathways of silybin and 2,3-dehydrosilybin in nonaqueous solutions. The oxidation mechanism of both flavonolignans differs and depends strongly on their chemical structure. The cyclic voltammetry, UV/Vis and IR spectroelectrochemistry were used for identification of electrooxidation (semiquinone) intermediates. HPLC with diode array detection was applied for identification of oxidation and degradation products. Molecular orbital calculations supported the experimental findings.
