Metabolite Identification

Common Name

(-)-Epiafzelechin

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 hibiscus teas (Hibiscus sabbariffa), green bell peppers (Capsicum annuum), muscadine grapes (Vitis rotundifolia), white mustards (Sinapis alba), and black plums (Syzygium cumini). 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. Based on a literature review a significant number of articles have been published on (-)-Epiafzelechin.
