Anthocyanidins were synthesized to study the effect of methoxy substitution on the B ring to their antioxidant property. Comparative FRAP studies show 2′- and 4′-methoxy substituents have higher antioxidant activities, which may be attributed to both resonance and inductive effects.Graphical abstract:Anthocyanidins as reducing agents Electronic supplementary material The online version of this article (doi:10.1186/s40064-015-1250-x) contains supplementary material, which is available to authorized users.
