Synthetic anthocyanidins and their antioxidant properties [PDF]
SpringerPlus, 2015 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.

Molecular identification of 1-Cys peroxiredoxin and anthocyanidin/flavonol 3galactosyltransferase from proanthocyanidin-rich young fruits of persimmon ( Thunb.) [PDF]
, 2009 Fruits of persimmon (Diospyros kaki Thunb.) accumulate large amounts of proanthocyanidins (PAs) in the early stages of development. Astringent (A)-type fruits remain rich in soluble PAs even after they reach full-mature stage, whereas non-astringent (NA)-
