Drupanol is a naturally occurring phenol that has been isolated from the seeds of Psoralea drupaceae.[1][2] Although drupanol is sometimes said to be the same compound as bakuchiol, the two compounds are in fact distinct; they have the same molecular formula and weight but different chemical structures and hence are structural isomers.[1] Bakuchiol has been found to possess antiandrogenic activity in vitro.[3]
