It is isolated from Ardisia japonica and exhibits anticancer properties. It has a role as an antineoplastic agent and a plant metabolite. It is a bridged compound, a cyclic ether, a hexacyclic triterpenoid, a secondary alcohol, a trisaccharide derivative and a triterpenoid saponin. It is functionally related to a (3beta,16alpha)-13,28-epoxyoleanane-3,16,30-triol. It derives from a hydride of an oleanane."}]
