Isolated from Cerbera manghas, it exhibits cytotoxic activities against oral human epidermoid carcinoma (KB), human breast cancer cell (BC) and human small cells lung cancer. It has a role as a metabolite and an antineoplastic agent. It is a cardenolide glycoside, a monosaccharide derivative, a tertiary alcohol and an epoxy steroid. It is functionally related to a tanghinigenin."}]
