Isolated from the aerial parts of Lysimachia clethroides, it exhibits antineoplastic activity. It has a role as an antineoplastic agent and a plant metabolite. It is a triterpenoid saponin, a hexacyclic triterpenoid, a cyclic ether, a cyclic terpene ketone and a tetrasaccharide derivative. It derives from a hydride of an oleanane."}]
