It has been isolated from the fruit bodied of Ganoderma tsugae and exhibits cytotoxic activity against several different cancer cell lines. It has a role as an antineoplastic agent and a fungal metabolite. It is a triterpenoid saponin, an acetate ester and a monosaccharide derivative. It derives from a hydride of a lanostane."}]
