Abstract

The main objective of this study was to determine the chemical composition of essential oils (EOs) obtained from leaf, old branches, and young branches of a coniferous species Calocedrus decurrens acclimated to Corsica. The analytical investigation was conducted by GC(RI), GC-MS, pc-GC, and NMR. C. decurrens leaf, old branches, and young branches EOs contained α-pinene (11.2; 56.6; 22.3%), myrcene (13.4; 8.4; 9.7%), Δ-3-carene (31.3; 5.2; 11.1%), limonene (6.4; 5.1; 5.5%), terpinolene (6.9; 1.5; 3.2%), and pin-2-en-8-ol (4.2; 4.5; 10.4%) as major components, respectively. Special attention was paid to purifying and identifying four unusual pinane derivatives: pin-2-en-8-ol, pin-2-en-8-yl Acetate, pin-2-en-8-al, and methyl pin-2-en-8-oate. The last two are reported for the first time. View Full-Text
