It is isolated from the whole plants of Ardisia japonica and exhibits significant cytotoxicity against a panel of human cancer cell lines. It has a role as an antineoplastic agent and a plant metabolite. It is a bridged compound, a cyclic ether, a secondary alcohol, a trisaccharide derivative, a hexacyclic triterpenoid and a triterpenoid saponin. It is functionally related to a (3beta,16alpha)-13,28-epoxyoleanane-3,16-diol. It derives from a hydride of an oleanane."}]
