Flavonoid Glossary

The numbering of the three flavonoid parents are shown at the top. These are classified into various subclasses based on the degree of oxidation. This is illustrated for flavans but equally applies, where appropriate, for isoflavans and neoflavans.

flavan	isoflavan	neoflavan
flavanone	flavone	flavonol
flavan-3-ol	flavan-3,4-diol	dihydroflavonol
anthocyanidin	anthocyanin
