Theflavan-4-ols (3-deoxyflavonoids) areflavone-derivedalcohols and a family of flavonoids. Flavan-4-ols are colorless precursor compounds that polymerize to form redphlobaphene pigments.[1] They can be found in the sorghum.[2] Glycosides (abacopterinsA,B,C andD together withtriphyllin A and6,8-dimethyl-7-hydroxy-4‘-methoxyanthocyanidin-5-O-β-d-glucopyranoside) can be isolated from amethanol extract of the rhizomes ofAbacopteris penangiana.[3]
Flavanone 4-reductase is an enzyme that uses (2S)-flavan-4-ol and NADP+ to produce (2S)-flavanone, NADPH, and H+.
These compounds have absorption maxima of 564 nm.[4]
