title: Chemical investigations of essential oils from endemic Cupressaceae trees from New Caledonia.
abstract: The volatile components obtained by hydrodistillation of leaves of C. neocaledonica Dummer, C. sulcata (Parlatore) Schlechter and N. pancheri (Carrière) de Laubenfels from New Caledonia were investigated for the first time by a combination of GC and GC-MS analysis, and compared with the heartwood oil compositions of the three species. The essential oils from C. sulcata and C. neocaledonica leaves contain a majority of monoterpenes while the leaf oil of N. pancheri is characterized by a high level of sesquiterpenoids. On the basis of the sesquiterpenoid composition of the wood- and leaf oils, N. pancheri is closely related to both New Caledonian Callitris spp. However, C. sulcata and C. neocaledonica oils remain distinct from N. pancheri and the Australian Callitris oils by the presence of compounds biosynthetically related to the bisabolyl cation, mainly barbatenes and thujopsene.
