Description

(-)-Epiafzelechin belongs to the class of organic compounds known as flavan-3-ols. These are flavans that bear and hydroxyl group at position 3 (B ring), but not at position 4. Thus, (-)-epiafzelechin is considered to be a flavonoid (-)-Epiafzelechin is found, on average, in the highest concentration within a few different foods, such as teas (Camellia sinensis), red tea, and herbal tea and in a lower concentration in green tea and black tea (-)-Epiafzelechin has also been detected, but not quantified in, several different foods, such as mexican oreganos (Lippia graveolens), vaccinium (blueberry, cranberry, huckleberry), italian oreganos (Origanum X majoricum), butternuts (Juglans cinerea), and corns (Zea mays). This could make (-)-epiafzelechin a potential biomarker for the consumption of these foods (-)-Epiafzelechin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. epiafzelechin is found in Acacia catechu , Actinidia chinensis , Afzelia sp., Aiouea hammeliana, Artocarpus dadah, Artocarpus fretessi Hassk, Artocarpus reticulatus Miq, Bauhinia racemosa, Bergenia ligulata , Camellia sinensis , Cassia abbreviata , Cassia fistula , Cassia javanica , Cassia roxburghii, Cassia sieberiana, Cassia spp., Cassipourea gummiflua, Celastrus orbiculatus, Cochlospermum gillivraei, Crateva religiosa, Desmoncus polyacanthos , Desmoncus polycanthus, Dicranopteris pedata, Ephedra sinica , Ephedra sp., Eucalyptus calophylla, Eysenhardtia subcoriacea Pennell, Ficus cordata, Ginkgo biloba , Juniperus communis , Kandelia candel, Larix gmelinii, Larix sibirica, Nothofagus fusca, Paraburkholderia phymatum, Pelargonium reniforme, Phyllanthus emblica, Pinalia floribunda, Prunus persica , Saxifraga ligulata, Senegalia catechu, Taxus chinensis, Tsuga chinensis, Typha capensis, Typha capensis (Rohrb.) N. E. Br , Wisteria floribunda, Xanthoceras sorbifolia and Ziziphus jujuba. epiafzelechin was first documented in 2011 (PMID: 21070009). Based on a literature review a small amount of articles have been published on (-)-Epiafzelechin (PMID: 34271878) (PMID: 34068829) (PMID: 33922460) (PMID: 33842675).
