Afzelechin
Afzelechin is a flavan-3-ol, a type of flavonoid. It exists as at least 2 major epimers (afzelechin and epi-afzelechin). It is produced through the transformation of cis-3,4lecuopelargonidin through the action of (2R,3S)-catechin:NADP+ 4-oxidoreductase. Afzelechin can be found in many plants native to Asia such as: Astilbe rivularis (also known as waterside astilbe), Bergenia ligulate (also known as Paashaanbhed in Ayurveda traditional Indian medicine), and Wisteria floribunda (Japanese wisteria). Afzelechin also occurs in barley and rye as a member of the proanthocyanidins found in these crop plants. Afzelechin exhibits moderate inhibitory effects on tumor necrosis factor alpha (TNF-α) induced nuclear factor kappa-B (NF-kB) activation in HepG2 cells (PMID: 21985227).

Gallocatechin 3'-gallate
Gallocatechin 3-gallate is a member of the class of compounds known as catechin gallates. Catechin gallates are organic compounds containing a gallate moiety glycosidically linked to a catechin. Thus, gallocatechin 3-gallate is considered to be a flavonoid lipid molecule. Gallocatechin 3-gallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Gallocatechin 3-gallate can be found in tea, which makes gallocatechin 3-gallate a potential biomarker for the consumption of this food product.
