Common NameEmbelin
DescriptionEmbelin, also known as embelic acid or embelate, belongs to the class of organic compounds known as p-benzoquinones. These are benzoquinones where the two C=O groups are attached at the 1- and 4-positions, respectively. Embelin is found in Aegiceras corniculatum, Apis cerana, Ardisia colorata, Ardisia crenata , Ardisia japonica, Ardisia oxyphylla, Embelia ribes , Embelia schimperi, Embelia tsjeriam-cottam, Lysimachia punctata, Myrsine africana , Myrsine melanophloeos, Myrsine seguinii, Myrsine umbellata, Rapanea laetevirens and Rapanea spp.. Embelin was first documented in 2000 (PMID: 11054840). Embelin is an extremely weak basic (essentially neutral) compound (based on its pKa) (PMID: 12963150) (PMID: 15890461) (PMID: 17124632).
