Erythrodiol, an Oleanane-type Triterpenoid: Natural Resources and Medicinal importance

Abstract

Erythrodiol, is a naturally abundant biologically active triterpenoid. It is the biosynthetic precurso r of pentacyclic oleanae-type triterpenic acids in plants. This is a dihydroxy triterpenoid having beta-amyrin type fused pentacyclic (6-6-6-6-6) carbon skeleton Herein, we have reviewed the various plant resources of this oleanane-type triterpenoid erythrodiol. Various pharamacological activities of erythrodiol have also been discussed.
