Isolated from the roots of Euphorbia kansui, it exhibits anti-cancerous activity. It has a role as a metabolite and an antineoplastic agent. It is a cyclic terpene ketone, a fatty acid ester, a tetracyclic diterpenoid and a dodecanoate ester. It is functionally related to a 2,3-dimethylbutyric acid, an ingenol, a dodecanoic acid and a hexadecanoic acid."}]
