Source-derived summary

The flavan-4-ols (3-deoxyflavonoids) are flavone-derived alcohols and a family of flavonoids. Flavan-4-ols are colorless precursor compounds that polymerize to form red phlobaphene pigments. They can be found in the sorghum. Glycosides (abacopterins A, B, C and D, together with triphyllin A and 6,8-dimethyl-7-hydroxy-4‘-methoxyanthocyanidin-5-O-β-d-glucopyranoside) can be isolated from a methanol extract of the rhizomes of Abacopteris penangiana.

Known flavan-4-ols

Apiforol

Luteoforol

Metabolism

Flavanone 4-reductase is an enzyme that uses (2S)-flavan-4-ol and NADP+ to produce (2S)-flavanone, NADPH, and H+.

Spectral data

These compounds have absorption maxima of 564 nm.

Editorial summary

The public source identifies “Flavan-4-ol” as chemical compound. This brief keeps that definition visible, then builds a research path around Flavan-4-ol, chemical and compound.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 87-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Flavan-4-ol, chemical and compound providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Flavan-4-ol”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q3560517. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
