Flavonoids: Nature 's Antioxidant Arsenal

Flavonoids audent of the e largett and mogt studied classes of plant polyfenols, with over 6,000 identified compounds. Their basic structure consists of a 15-karbon sketeton arranged as two aromatic rings (A and B) connected by a threekarbon bridge, forming a heterocyclic ringer (C). The specific substitution pertegns on these rings detere the subfamiliation. Major subgroups include flavonols (quercetin, kaempethion), flavonis (luteolin), flavanonin (flavanones (hesperetin, flamininfinium), flavanis (flavanium), flavans (flavans), flavans (patänicientech, picides, fati@@
