“…9) is the major compound of various Abies species, 13,15,27 it was found at a relatively low concentration in our study. In addition to these terpenes, three C 6 -aldehydes and two C 6 -alcohols, which contribute the green odour to green leaves, 28 were identified by GC-MS.…”

Volatile components in the needles of Abies nephrolepis (Khingan fir), a conifer native to Korea, were extracted by simultaneous distillation-extraction. Gas chromatography-mass spectrometry using two types of capillary column with different polarities (DB-5MS and DB-WAX) revealed that α-pinene (23.2%) is the most abundant compound, followed by limonene (12.7%), bornyl acetate (9.9%) and β-caryophyllene (10.8%). Aromaactive compounds of A. nephrolepis were determined using gas chromatography-olfactometry by aroma extract dilution analysis. α-Pinene showed the highest flavour dilution factors, ranging from 3 8 to 3 9 with characteristic pine aroma. (Z)-3-Hexenal and γ-terpinene were also identified as important aroma-active compounds.

“…The identified compounds of seed and cone essential oils are shown in Table 1. The main terpene group detected in both seed and cone essential oils were monoterpene hydrocarbons, constituting 93 g/100 g and 79 g/100 g, respectively, like in the Abies concolor needle essential oils, where the concentration of this terpene group was about 90% [7,8,9,10]. Monoterpene hydrocarbons were also a predominant chemical group in the oils that were isolated from seeds and cones of both Abies alba [15,16] and A. koreana [14,15,16], The dominant monoterpene hydrocarbons and at the same time the main constituents of examined seed essential oil were limonene (47 g/100 g) and α-pinene (40 g/100 g).…”

“…In contrast to a few manuscripts that reported needle volatiles [7,8], variability of needle terpenes during seasonal changes [9,10], as well of needle essential oils of firs growing in urban environment [11], and two papers dealing with seed fatty acids of white fir [12,13], no attention has been paid to intact seed or cone essential oils, both with respect to their chemistry and biological functions.…”

The chemical composition, including the enantiomeric excess of the main terpenes, of essential oils from seeds and cones of Abies concolor was studied by chromatographic (GC) and spectroscopic methods (mass spectrometry, nuclear magnetic resonance), leading to the determination of 98 compounds. Essential oils were mainly composed of monoterpene hydrocarbons. The dominant volatiles of seed essential oil were: limonene (47 g/100 g, almost pure levorotary form) and α-pinene (40 g/100 g), while α-pinene (58 g/100 g), sabinene (11 g/100 g), and β-pinene (4.5 g/100 g) were the predominant components of the cone oil. The seed and cone essential oils exhibited mild antibacterial activity, and the MIC ranged from 26 to 30 μL/mL against all of the tested bacterial standard strains: Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, Escherichia coli, and Klebsiella pneumoniae. The cytotoxic studies have demonstrated that tested essential oils were cytotoxic to human skin fibroblasts and human microvascular endothelial cells at concentrations much lower than the MIC. The essential oils from A. concolor seeds and cones had no toxic effect on human skin fibroblasts and human microvascular endothelial cells, when added to the cells at a low concentration (0–0.075 μL/mL) and (0–1.0 μL/mL), respectively, and cultured for 24 h.

“…In addition to variation within a population, seasonal variation in the composition of volatile oll has been observed in a variety of species (von Rudloff 1975;Hedin Okamoto et al 1981;Pitarevic et al 1984;Marhuendra & de la Lastra 1986;Cabo et al 1987;Wagner et al 1989;Whiffen & Hyland 1989;Buben et al 1990). This was also investigated in this study of sweet gale.…”

Variation of leaf gland volatile oil within a population of sweet gale (Myrica gale) (Myricaceae)

1992

SummaryThe leaf gland volatile oils of ten sweet gale plants from a Scottish population were extracted in early summer. The results differed notably from reports of other populations in respect of the sesquiterpenes, [3-elemenone and germacrone, which were major components of the volatile oll. Three dihydrochalcones were also detected in the volatile oll. Variation within the population existed, particularly with respect to the relative importance of germacrone.Five plants were resampled in late summer and exhibited a marked reduction in 13-elemenone, a lesser reduction in germacrone and changes in the proportions of some monoterpenes.
