Isolated from Physalis longifolia, it exhibits antineoplastic activity. It has a role as a metabolite, an antineoplastic agent and a plant metabolite. It is a steroid sulfate, a delta-lactone, a 27-hydroxy steroid, a 4-hydroxy steroid, an ergostanoid, a primary alcohol, a withanolide and an epoxy steroid. It is functionally related to a withaferin A."}]
