Flavonoids are a class of plant secondary metabolites. Their name is derived from the Latin word flavus meaning yellow, their colour in nature. In higher plants, flavonoids are involved in UV filtration, symbiotic nitrogen fixation and floral pigmentation. They are the most important plant pigments for flower coloration producing yellow or red/blue pigmentation.
The term flavonoids is very generic, and is used to describe any organic molecular entity whose stucture is based on derivatives of a phenyl-substituted 1-phenylpropane possessing a C15 or C16 skeleton, or such a structure condensed with a C6-C3 lignan precursors.
The following are three of the main classes of flavonoids, although many more exist:
Child Classes: a 3'-hydroxy-flavonoid (19), a 3'-methoxyflavonoid (2), a 4'-methoxyflavonoid (0), a 5'-methoxyflavonoid (0), a chalcone (29), a flavan (52), a flavone (197), a neoflavonoid (1), a pterocarpan (14), an anthocyanin (80), an aurone (11), an isoflavonoid (49)
