Chemical compositions of essential oils of five introduced conifers in Corsica

Abstract

The aim of this survey was to determine the chemical composition of essential oils (EO) of five conifers acclimated in Corsica by GC(RI), GC-MS and 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.

“…menziesii ). Additionally, similar chemical profile was reported for DEO from Austria, [5] Bulgaria, [6,8] and Corsica [15] suggesting that trees introduced in these parts of Europe also belong to the ‘coastal’ chemotype of var. menziesii .…”

Original Contributions to the Chemical Composition, Microbicidal, Virulence-Arresting and Antibiotic-Enhancing Activity of Essential Oils from Four Coniferous Species

“…Camphene, α-pinene, β-pinene and limonene are prevalent among the monoterpene hydrocarbons. The EO compositions isolated from P. abies [11], L. decidua and P. menziesii [34] are similar to the previously published papers. For the EO extracted from P. abies, the content in compounds with oxygen is significantly higher than in other oils, i.e., 11.08% for bornyl acetate, 9.40% for manool, 3.87% for α-cadinol, and 2.15% for α-muurolol.…”

An Integrative Volatile Terpenoid Profiling and Transcriptomics Analysis for Gene Mining and Functional Characterization of AvBPPS and AvPS Involved in the Monoterpenoid Biosynthesis in Amomum villosum

“…Bornyl acetate was also found in other plant species, including liverwort ( Adam and Croteau, 1998 ; Ab Ghani et al, 2016 ), Korean fir and Larix decidua (Pinaceae family) ( Jeong et al, 2007 ; Garcia et al, 2017 ), Sabina chinensis (Cupressaceae family) ( Gu et al, 2018 ), Lippia sidoides (Verbenaceae family) ( de Morais et al, 2016 ), Artemisia montana , and Chrysanthemum indicum (Asteraceae family) ( Stoianova-Ivanova et al, 1983 ; Kunihiro et al, 2017 ). Bornyl acetate was distributed in the leaves of most of the plants mentioned above, but was especially rich in the seeds of A. villosum .…”
