The molecule is a triterpenoid saponin that is composed of (3beta,16alpha)-13,28-epoxyoleanane-3,16-diol having a beta-D-Glcp-(1->2)-{beta-D-Xylp-(1->2)-{beta-D-Glcp-(1->3)-[beta-D-Glcp-(1->4)]-beta-D-Glcp-(1->3)}-beta-D-Glcp-(1->4)}-alpha-L-Arap moiety attached to position 3 by a glycosidic linkage. It is isolated from 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 heptasaccharide derivative, a bridged compound, a cyclic ether, a secondary alcohol, a hexacyclic triterpenoid and a triterpenoid saponin. It derives from a (3beta,16alpha)-13,28-epoxyoleanane-3,16-diol. It derives from a hydride of an oleanane.
