The electrochemical properties of a series of sterically hindered o -benzoquinones in aprotic solvents were examined. The reaction of O 2 and KO 2 with o -benzoquinones and electrogenerated o -semiquinone radical anions was studied. The formation of o -semiquinone radical anions in the reactions of KO 2 with the studied o -quinones was detected using UV-visible and ESR spectroscopy. The influence of the test compounds on lipid peroxidation was considered at the molecular and tissue levels in vitro . In the most cases, o -quinones exhibit antioxidant activity, which varies depending on the type of lipid substrate.
