The molecule is a triterpenoid saponin isolated from the roots of of the Madagascan plant Albizia gummifera and has been shown to exhibit cytotoxicity against human ovarian cancer cell line. It has a role as an antineoplastic agent and a plant metabolite. It is an enoate ester, a pentacyclic triterpenoid and a triterpenoid saponin. It derives from a hydride of an oleanane.
