Abstract

Flavonoids are a large group of natural phenolic compounds contained in high concentrations in vegetables, fruits, etc. Antioxidant and redox properties of some flavonoids such as catechin, quercetin, dihydroquercetin, and rutin were investigated in this work. Optimal concentration and time of action of flavonoids were obtained. To determine the more effective range of antioxidant activity, mathematical models and the response surfaces of investigated flavonoids were determined using methods of experiment design. Oxidation potentials of the compounds were also obtained, E=0.3÷0.4 V. Moreover, the antioxidant activity of flavonoids depends on the redox properties and the structure of the flavonoids. The antioxidant activity of flavonoids, which is correlated to reversible potentials for this compound is good. Finally, the use of these substances as antioxidants with therapeutic effects has been recommended in human diet.
