Androstane-4, 6, 8 (9), 13 (14)-tetraene-3, 11, 16-triketone and application thereof

The invention discloses a polyene high-oxidation androstane compound, i.e., androstane-4, 6, 8 (9), 13 (14)-tetraene-3, 11, 16-triketone. The compound is extracted from epigynum auritum plant. Experiments prove that the compound has an obvious suppression effect on Balb/c mouse spleen lymphopoiesis stimulated by ConA (concanavalin) and has activity equivalent to that of the conventional immunosuppression active substances, i.e., triptolide and dexamethasone.
