Defensive steroids from a carrion beetle (Silpha novaboracensis).

J Meinwald1, B Roach, T Eisner.   

Abstract

Two novel steroids, 3α,7β-dihydroxy-14β-pregn-4-en-15,20-dione (1) and 3α,7β, 20ξ-trihydroxy-14β-pregn-4-en-15-one (4), have been characterized from the rectal gland ofSilpha novaboracensis (Coleoptera: Silphidae). Judging from the function of comparable pregnanes in another species ofSilpha, the compounds may play an antipredator role.
