[Relationship between the antioxidant effect of flavonoids and their effect on the vasodilating function of endothelium under endothelial dysfunction conditions].

A relationship between the vasodilating activity of flavonoids under conditions of endothelial dysfunction in experimental diabetes and their antioxidant effect is established. Flavicin and quercetin show the maximum influence on the vasodilating function of endothelium and exhibit more pronounced antioxidant activity under conditions of endothelial dysfunction.
