Isolated from Antrodia cinnamomea and Antrodia camphorata, it exhibits cytotoxic and anti-inflammatory activity. It has a role as an antineoplastic agent, an anti-inflammatory agent and a plant metabolite. It is a 3-oxo steroid, a 7-oxo steroid, an 11-oxo steroid, a steroid acid, a monocarboxylic acid and an ergostanoid."}]
