Afzelechin is a flavan-3ol, a type of flavonoids. It can be found in Bergenia ligulata (aka Paashaanbhed in Ayurveda traditional Indian medicine)[1].

Metabolism

(2R,3S)-catechin:NADP+ 4-oxidoreductase transforms cis-3,4-leucopelargonidin into afzelechin[2].

Glycosides

Arthromerin A (afzelechin-3-O-β-D-xylopyranoside) and arthromerin B (afzelechin-3-O-β-D-glucopyranoside) are afzelechin glycosides isolated from the roots of Arthromeris mairei[3].

(+)-afzelechin-O-β-4'-D-glucopyranoside can be isolated from the rhizomes of Selliguea feei[4].

Proanthocyanidins

dimers

Afzelechin-(4alpha→8)-afzelechin (molecular formula : C30H26O10, molar mass : 546.52 g/mol, exact mass : 546.152597, CAS number : 101339-37-1, Pubchem CID : 12395) is a B type proanthocyanidin.
Ent-epiafzelechin-3-O-p-hydroxybenzoate-(4α→8,2α→O→7)-epiafzelechin) is an A-type proanthocyanidin found in apricots (Prunus armeniaca)[5].

Trimers

Selligueain A (epiafzelechin-(4β-8,2β-0-7)-epiafzelechin-(4β-8)-afzelechin) is a A type proanthocyanidin.
