Isolated from the methanolic extract of the leaves of Symplocos lancifolia, it exhibits antibacterial activity. It has a role as a plant metabolite. It is a pentacyclic triterpenoid and a triterpenoid saponin. It is functionally related to an asiatic acid. It derives from a hydride of an ursane."}]
