“…The forest operation activities leave important quantities of foliage which should be transformed and valorized according to the concept of responsible and sustainable forest management. The extraction of essential oils ( ) and Labrador tea (Ledum groenlandicum L.) represents, particularly in eastern Canada, one of the main modes of foliar valorization, and therefore, there are abundant data in the literature on the EOs from these species (Risi and Brûlé 1945;Shaw 1953;von Rudloff 1961von Rudloff , 1967von Rudloff , 1972Hunt and von Rudloff 1974;von Rudloff and Granat 1982;Simard et al 1988;Hachey et al 1989;Belleau and Collin 1993). These studies reported very instructive information on the composition of these oils as they depend on various parameters such as extraction procedure, extraction season, tree age, intraspecific and interspecific aspects of the trees, etc.…”

Essential oils (EOs) were steam-extracted from the needles and twigs of balsam fir, black spruce, white spruce, tamarack, jack pine and eastern white cedar that remained after logging in eastern Canada. These EOs, similarly to that from Labrador tea and other commercial EOs from Chinese cinnamon, clove and lemon eucalyptus, exhibited many common constituent compounds (mainly α-pinene, β-pinene, limonene and bornyl acetate) making up 91% of each oil based on gas chromatography-mass spectrometry analysis. All of these oils exhibited antibacterial properties, especially when examined in closed tube assay compared to the traditional 96-well microliter format. These antimicrobial activities (minimum inhibitory concentration ≥ 0.2% w/v), comparable to those of exotic EOs, were shown against common pathogenic bacteria and fungi. The antioxidant potential of the boreal samples was determined by the 1,1-diphenyl-2-picrylhydrazyl radical scavenging (concentration providing 50% inhibition ≥ 7 mg/ml) and reducing power methods. Finally, this investigation revealed some boreal EOs to be potential antimicrobial and antioxidant agents that would notably benefit products in the personal hygiene and care industry.

“…The composition of the hydrocarbon fraction of the oils analyzed by Pauly et al (13) can be considered to be in agreement with our results, although somewhat higher percentages of α−pinene (around 73 %) were found by Pauly et al The higher oil yield (0.7 % vs. 0.4% on average) obtained from C. sempervirens leaves with higher percentages of α−pinene can be explained that Pauly et al (13) used ground fresh leaves whereas in the present work the grinding of fresh branchlets was omitted for simplicity. Sample preparation influences significantly both the yield and composition of the oil as demonstrated by Hachey et al (14) in case of needles and twigs of black spruce. They found that the oil yield almost doubled while the percentage of low boiling compounds such as α−pinene and camphene was markedly increased after maceration of the plant material.…”

In order to differentiate two varieties of Cupressus sempervirens, volatile foliage isolates obtained from 12 trees of variety horizontalis and 12 trees of var. pyramidalis were analyzed by GC and GC/MS. About 86-87% of total peak areas of chromatograms consist of monoterpenes and evaluating their composition in qualitative and quantitative manner they do not show significant differences with regard to varieties. Some increments of terpinen-4-ol, α−terpineol and α−terpinyl acetate was recognizable in the variety horizontalis, while the variety pyramidalis contained germacrene D and abietadiene to somewhat higher level. On the other side, a higher percentage of α−fenchene than that of camphene and the presence of a monoterpene hydrocarbon sylvestrene were found to bear some chemotaxonomic value for the taxon C. sempervirens.

“…These species also contain carene and limonene in quite high amounts. 7,8 Appreciable amounts of limonene/β-phellandrene and bornyl acetate, but little carene, were found in needle extracts of P. omorika (native), P. orientalis (arboretum specimen) and P. jezoensis (cultured). 20 In needles of oriental spruce, αand β-pinene, camphene, β-myrcene, α-terpinolene, borneol, terpineols, βcaryophyllene, germacrene and cadinol isomers are other significant compounds.…”

Volatile needle and wood extracts of oriental spruce obtained from trees grown naturally in eastern Black Sea regions and in an cultivated stand near Istanbul were analysed by GC-MS. Despite considerable differences in both tree-to-tree and natural-to-cultivated aspects, the needle and wood extracts exhibit characteristic compounds, which might be of chemotaxonomic interest. The monoterpenes δ-3-carene, limonene and bornyl acetate dominate in the needles, whereas the appreciable amounts of labdadienol isomers and high content of diterpenoids characterize the wood extracts.
