Chemical compositions of essential oils of five introduced conifers in Corsica

C NMR. L. decidua needle and wood EOs contained as majors components: α- and β-pinenes, germacrene D (needles) and bornyl acetate (wood). The EOs of needles, wood and cones of P. menziesii were characterised by β- and α-pinenes, terpinen-4-ol, sabinene, terpinolene (needles and wood), Δ-3-carene (wood) and limonene (cones). Needles and wood EOs of P. ponderosa contained as major components: β- and α-pinenes, Δ-3-carene (wood) and estragole (needles). S. giganteum EOs of foliage and wood were rather similar and dominated by α-pinene, and safrole. The EOs of leaf, wood and cones from C. japonica were very similar, and exhibited α-pinene, sabinene, β-elemol and kaurene as major constituents. It appeared that EO compositions of some species were different from reported literature data.
