Four furanoid terpenic compounds, α-clausenan, rosefuran (γ-clausenan) and diclausenans A and B, were isolated from the essential oil of the leaves of Clausena willdenovii.Their structures were determined by chemical and spectral data.The occurence of a high concentration of rosefuran is noteworthy.Selenium dioxide oxidation of diclausenan gave an unusual product, identified as an epoxy-dicarbonyl compound. - Keywords: Clausena willdenovii; Rutaceae; furanoterpenes; α-clausenan; γ-clausenan (rosefuran); diclausenans A and B.
