The essential oils of leaves and seeds ofClausena anisata(Rutaceae) from Cameroon were analyzed by GC/FID, GC/MS and GC-sniffing. The oils are characterized by a high percentage of oxygenated monoterpenes. The major components in the leaf oil were (Z)-tagetenone (26.8%), (E)-tagetenone (19.2%), (E)-nerolidol (11.5%) and germacrene D (9–2%), while in the seed oil the major components were (Z)-tagetenone (15.3%), (E)-tagetenone (14.8%), (E)-nerolidol (10.3%), myrcene (7.4%), β-caryophyllene (7.4%), 3-carene (3–9%) and α-humulene (3.5%). Some interesting minor compounds have been found, namely myrcenone (= ipsdienone), (E)-2(3)- and (Z)-2(3)-tagetenone epoxide and ambrettolide (mainly in the seed oil).
