Chloroform/Methanol extraction of the bark ofCedrela salvadorensis (Meliaceae), followed by chromatography afforded the crystalline C28H34O7 terpene. The structure first proposed by spectroscopy is confirmed by this X-ray analysis as 7α-acetyloxy-14,15:21,23-diepoxy-4,4,8-trimethyl-d-homo-24-nor-17-oxachola-1,20,22-triene-3,16,-dione.

The limonoid bitter principles are a class of C26 degraded triterpenes believed to arise as oxidation products of tetracyclic triterpenes. A second group of related bitter principles, the simaroubolides, occur as further breakdown products in this series (30, 55, 97).
