For comparative purposes, a quantitative estimation of antioxidant activity of phenolic compounds of different classes was conducted by way of the polarography method, via the ADP-Fe2+ model of the induced ascorbate-dependent lipid peroxidation of rat liver microsomes within an in-vitro system. As a result, it was recognized that the antioxidant properties of phenolic compounds depend on the nature and chemical structure of several substances. In respect of such activity, leaders in the classes of investigated polyphenolic compounds are: Propyl gallate = Gallotannin (Phenolcarboxylic acids and their derivatives) > Quercetin = Myricetin (Flavonols) > Luteolin (Flavo n) = Mangiferin (Xanthones) > Kaempferol (Flavonols) = Catechin (Flavans). Thus, the assessment of the inhibition ability of the lipid peroxidation of microsomes by phenolic compounds can be used as an accessible test for the preliminary quantitative estimation of their antioxidant properties.
