Neoflavonoids are a class of polyphenolic compounds.[1] While flavonoids (in the narrow sense) have the 2-phenylchromen-4-one backbone, neoflavonoids have the 4-phenylchromen backbone with no hydroxyl group substitution at position 2.
Neoflavonoids include 4-arylcoumarins (neoflavones), 4-arylchromanes, dalbergiones and dalbergiquinols.
- Neoflavones[1] are derived from the 4-phenylcoumarin (or 4-aryl-coumarin) backbone (C15H12O2).[2] The first neoflavone isolated from natural sources was calophyllolide from Calophyllum inophyllum seeds (1951).[3] It is also found in the bark and timber of the plant Mesua thwaitesii, endemic to Sri Lanka.[4]
- Neoflavenes possess the 4-phenylchromen backbone (C15H10O2). Dalbergichromene, extracted from the stem-bark and heartwood of Dalbergia sissoo, is an example of such compounds[5]
- Coutareagenin (5-hydroxy-7-methoxy-4-(3,4-dihydroxyphenyl)-2H-benzo-1-pyran-2-on) found in Hintonia latiflora[6]
- Dalbergin
- Nivetin isolated from Echinops niveus[7]
