ent-epiafzelechin

Description

Ent-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, ent-epiafzelechin is considered to be a flavonoid. ent-epiafzelechin is found in Cassia fistula. Based on a literature review very few articles have been published on Ent-epiafzelechin.
