Flavonoids are a large group of polyphenolic compoundspossessing a basic flavan moiety with two aromatic rings(A- and B-ring) interconnected by a three-carbon-atomheterocyclic ring (C-ring). The most widespread flavonoidscontain a double bond between C-2 and C-3 and a ketofunction at C-4 of C-ring. Here, the double bond is attachedto B ring at C-2 (flavone) or at C-3 (isoflavone). As a resultof a number of further modifications on all three rings,particularly on C ring, flavonoid s represent one of the largestand the most diverse class of plant secondary metabolites.
