Bioflavonoids are fundamentally a class of natural benzo-γ-pyran derivatives and they possess important antioxidant activities. Flavone (e.g. apigenin, luteoline), flavonol (e.g. quercetin, myricetin), flavonolols (e.g. taxifolin), flavan-3-ols (e.g. catechin, epigallocatechin), flavonone (e.g. hesperetin, naringenin), anthocyanidin (e.g. cynidin, delphidin), isoflavone (e.g. genistein, daidzein).

Bioflavonoids usually observed in fruits and vegetables, show several biological effects including free radical-scavenging activity. For example, Quercetin is a flavonol, acknowledged extremely for its ability to protect DNA from oxidative damage resulting from the attack of ˙OH, H2O2, and O2˙− on the DNA oligonucleotides.

On the other hand, anthocynidins (cynidin) can donate a single electron to a free radical from –OH groups attached to the phenolic rings and this electron stabilizes and inactivates the free radical. Consequence of the overall result is the termination of damaging oxidative chain reactions.
