“…Almost all cypress trees (23 of 24 trees) contain sylvestrene, even though its percentage is very small (~0.2 %). This monoterpene hydrocarbon seems to possess some chemotaxanomic value since we did not encounter it in following conifer species grown in Turkey: Pinus, Abies, Picea, Cedrus (18,19 and unpublished results).…”

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.

“…In mass spectrometric detection, electron impact ionization is used as a first-choice option, since the initial identification of chemical compounds can be based on mass spectral similarity with the in-built mass libraries (NIST, Wiley) or various online sources. For confirmation of target compounds identity, retention times of respective standards could be used, or calculated Kovats retention indices (KI) may be compared with literature data [ 116 , 118 , 123 , 126 , 127 ]. The amount of compounds present in the solid material or emitted to the air can be expressed exactly using calibration curves or as an equivalent of one compound (e.g., toluene) [ 71 ].…”

Volatile Organic Compounds (VOCs) from Wood and Wood-Based Panels: Methods for Evaluation, Potential Health Risks, and Mitigation

Volatile organic compounds (VOCs) are contained in various construction materials and interior equipment. Their higher concentrations in the indoor air are associated with negative effects on human health and are disputed in terms of health risk, since people spend a considerable part of their lifetime indoors. Therefore, the presence of VOCs in indoor air is a case of concern regarding sick building syndrome (SBS). From a historical point of view, wood and wood-based panels represent a widely used material. Nevertheless, wood appears to be nowadays a product and a material of a sustainable future. Depending on wood extractives’ composition and an abundance of diverse wood species, different profiles of volatiles are emitted. In case of wood-based panels, the impact of adhesives and additives that are essentially applied aiming to adjust the panels’ properties is even enriching this cocktail of chemicals. This paper comprises the issue of VOCs emitted from wood and wood-based panels. The most abundant VOCs were summarized. The options of VOCs for analytical determination from these matrixes are described with their benefits and limitations.

“…3 Previously, nopol was identified as a volatile constituent of only a limited number of plant species, non of them belonging to the genus Anthemis and was usually only a minor contributor of the corresponding oils. [36][37][38][39][40][41][42][43][44][45][46][47] Interestingly, the authors of the mentioned paper 3 do not point out to this interesting fact of the abundant occurrence of nopol in A. werneri subsp. werneri oil.…”

Although there are more than two hundred taxa in the pharmacologically important genus Anthemis, essential oil composition is known only for a small number of them. This is the first report on the volatiles of A. segetalis Ten. GC and GC/MS analyses of the essential oil hydrodistilled from A. segetalis aerial parts enabled the identification of 155 constituents, representing 92.4% of the total oil. Major constituents of the oil were sabinene (19.5%), germacrene D (12.6%), terpinen-4-ol (6.2%) and 1,8-cineole (6.1%). Monoterpenoids (49.9%, especially those of thujane and p-menthane skeletons) and sesquiterpenoids (39.4%, predominantly those of germacrane-, cadinane-and caryophyllane-types) were found to be the most abundant compound classes. The comparison of the essential oil composition of other Anthemis species with the present one was used as an additional tool for the clarification of infrageneric relationships. The results support the treatment of Anthemis subg. Cota as a separate genus.
