Isolated from Antrodia cinnamomea and Antrodia camphorata, it exhibits antineoplastic activity. It has a role as a metabolite and an antineoplastic agent. It is an 11-oxo steroid, a 7-oxo steroid, a steroid acid, a 3alpha-hydroxy steroid, a 12alpha-hydroxy steroid, a monocarboxylic acid and a secondary alpha-hydroxy ketone."}]
