Enantiomeric Composition of Monoterpene Hydrocarbons in Different Tissues of Norway Spruce, Picea abies (L.) Karst. A Multi-dimensional Gas Chromatography Study.

Chemical Composition of Essential Oil and Hydrosol from Picea mariana Bark Residue

“…Thus, the pinenes represented more than two thirds of the black spruce bark essential oil, which showed the same characteristics as turpentine oils (Stevanovic and Perrin 2009), mostly from Pinus genus. For comparison, the chemical composition of Picea abies turpentine revealed the same pattern with a predominance of α-pinene (54.3%) and β-pinene (25.3%) (Borg-Karlson et al 1993), which confirmed that the volatile part of oleoresins from the Picea genus have compositions comparable to those of volatile oils from Pinus. The wood of P. mariana extracted with hexane was reported to contain α-pinene and β-pinene as the main monoterpenes as well, at 19% (heartwood) and 15% (sapwood) of the total hexane extract along with heavier diterpenoids (Pichette et al 1998).…”

As was reported for the turpentine oil of P. abies (Borg-Karlson et al 1993), three other main molecules 3-carene, limonene, and β-phellandrene were found in equivalent proportions in both the steam distilled and water distilled oils from black spruce bark studied in this research. Thus, the essential oil of P. mariana bark was mainly composed of hydrocarbon monoterpenes, whereas the P. mariana needle essential oil was constituted of 37% to 46.5% (Guenther 1952;Rudloff 1975) of the oxygenated monoterpene bornyl acetate.…”

Monoterpenes released from Apiaceae and the egg‐laying preferences of the carrot psyllid, Trioza apicalis

“…Mass spectra of all of the monoterpenes were compared with those of authentic samples. A multi-dimensional GC system (Borg- Karlson et al 1993), equipped with one DB-WAX and two chiral capillary columns, Cyclodex B and Lipodex E, was used for the determination of the enantiomeric composition of the main chiral monoterpene hydrocarbons. The identification of the monoterpene enantiomers was based on the retention times, using naturally occurring or synthetic reference compounds.…”

Host Selection in Tomicus piniperda L.: Composition of Monoterpene Hydrocarbons in Relation to Attack Frequency in the Shoot Feeding Phase

“…To determine the enantiomeric composition of the chiral monoterpene hydrocarbons, the samples were analyzed using a two-dimensional Varian 3400 GC instrument (Borg- Karlson et al, 1993). The GC program for chiral analyses was: 55 ∞C for 15 min, followed by 1 ∞C/min to 77 ∞C and kept at this level for 15 min.…”
