Electrochemical Oxidability of Antioxidants: Synergism and Antagonism in Mixes.

Aims: To investigate electrochemical oxidability of antioxidants to reveal synergistic and antagonistic effects in mixes.

Materials And Methods: Electrochemical oxidability of some widely used antioxidants, including uric acid, glutathione, trolox, ascorbic acid, gallic acid, Mexidol, and potassium fenozan, was investigated by the amperometric approach.

Results: All obtained electrochemical oxidability values correlate well with antioxidant activity parameters of the same compounds measured by other methods.

Comparative investigation of antioxidant activity of human serum blood by amperometric, voltammetric and chemiluminescent methods.

Introduction: A blood test can provide important information about the functional state of the antioxidant system. Malfunction of this system increases the concentration of free radicals and can cause oxidative stress. A difficulty in assessing oxidative stress is the lack of a universal method for determining the antioxidant activity (AOA) of blood components, because of their different nature.
