“…For these reasons, in our study, E. globulus showed the presence of volatile terpene compounds corresponding to MT and ST, and these results are comparable to those found in the literature [68,69]. P. radiata was the other species that presented similar chemical compounds also identified in previous works [70,71], where high amounts of MT (67.7%) and ST (27.7%) were reported.…”

Mediterranean climate regions have become more vulnerable to fire due to the extreme weather conditions and numerous Eucalyptus globulus plantation areas. The aim of this study is to analyze the fire hazard related to E. globulus in a forest fire scenario, based on the contrast of thermochemical parameters and their relationship with chemical properties, considering the predominant exotic forest species (E. globulus, Pinus radiata, Acacia dealbata, and Acacia melanoxylon) present in the Valparaiso region, Chile. The results revealed that although all of the studied species were highly flammable, E. globulus was extremely flammable, as its leaves contain high concentrations of essential oils, monoterpenes, and sesquiterpenes, which can generate a flammable atmosphere due to their low flashpoint and the strong negative influence shown between the essential oils, volatile terpenes, and limonene concentration. Moreover, the heat of combustion of E. globulus was positively correlated with its high essential oil contents. Finally, all of the studied species had low flashpoints and high heating values; therefore, they are predisposed to ignite in the presence of a heat source, releasing high amounts of energy during combustion, which contributes to the risk of the formation and spread of canopy fires among these tree formations.

“…A list of 20 target species was selected for various reasons: some are observed to be the most abundant species at the global scale (isoprene, β-pinene, α-pinene, limonene, ocimene, myrcene, sabinene, 3 -carene, and camphene) (Guenther et al, 1995;Sindelarova et al, 2014); others are emitted by pine trees (1.8 cineole) (Simon et al, 1994); some are present in pine needles (terpinolene, linalool, αphellandrene) (Ait Mimoune et al, 2013;Arrabal et al, 2012;Blanch et al, 2012;Kleinhentz et al, 1999;Ormeño et al, 2009;Simon et al, 1994); others are oxidation products, commercially available in pure solution (≥ 95 %) of monoterpenes (nopinone, citral); and some are highly reactive (α-terpinene, β-caryophyllene) (Atkinson et al, 2006) or usually monitored along with other BVOCs (p-cymene, γterpinene, 2-carene) (Hakola et al, 2017;Jones et al, 2014;Pankow et al, 2012). As only some of the target compounds were commercially available in certified gas mixtures (isoprene; β-pinene; α-pinene; limonene; p-cymene; myrcene; 3 -carene; ocimene; 1,8-cineole; camphor), a gas mixture containing all of the compounds reported previously was consequently generated via the vaporization of pure liquid standards inside an electropolished stainless steel canister.…”

Abstract. A new online gas chromatographic method dedicated to biogenic volatile organic compound (BVOC) analysis was developed for the measurement of a 20 BVOC gaseous mixture (isoprene; β-pinene; α-pinene; limonene; ocimene; myrcene; sabinene; Δ3-carene; camphene; 1,8 cineole; terpinolene; linalool; α-phellandrene; nopinone; citral; α-terpinene; β-caryophyllene; p-cymene; γ-terpinene; and 2-carene) at a time resolution of 90 min. The optimized method includes an online Peltier-cooled thermodesorption system sample trap made of Carbopack B coupled to a gas chromatographic system equipped with a 60 m, 0.25 mm internal diameter (i.d.) BPX5 column. Eluent was analysed using flame ionization detection (FID). Potassium iodide was identified as the best ozone scrubber for the 20 BVOC mixture. In order to obtain an accurate quantification of BVOC concentrations, the development of a reliable standard mixture was also required. Quantification of BVOCs was reported with a detection limit ranging from 4 ppt for α-pinene to 19 ppt for sabinene. The main source of uncertainty was the calibration step, stressing the need for certified gaseous standards for a wider panel of BVOCs. This new method was applied for the first time to measure BVOCs in a pine forest during the LANDEX episode 1 field campaign (summer 2017). All target BVOCs were detected at least once during the campaign. The two major monoterpenes observed were β-pinene and α-pinene, representing 60 % of the measured terpenoid concentration on average, while isoprene represented only 17 %. The uncertainties determined were always below 13 % for the six major terpenes.

“…β-caryophyllene was found to be a dominant compound in the essential oil of P. pinaster (Mimoune et al 2013). The principle constituents of the fruit oil of P. roxburghii from India were α-pinene (60.8%) and β-pinene (30.2%) (Qadir and Shah 2014).…”

The essential oils extracted by hydro-distillation of Pinus roxburghii wood, bark, and needles were analyzed by GC/MS, and their antibacterial and antioxidant activities were evaluated. Twenty-two, thirty-one, and twenty-eight compounds were identified in the essential oils of wood, bark, and needles, respectively. The major chemical constituents of wood's essential oil were caryophyllene (16.75%), thunbergol (16.29%), 3-carene (14.95%), cembrene (12.08%), α-thujene (10.81%), and terpinolen (7.17%). In bark, they were α-pinene (31.29%) and 3-carene (28.05%), and in needles, they were α-pinene (39%) and 3-carene (33.37%). Almost all of the essential oils were active against human pathogen bacteria, and the essential oils from bark and needles were active against the plant pathogen bacteria Ralstonia solanacearum and Pectobacterium carotovorum. Alternatively, Erwinia amylovora was resistant to all tested oils. The total antioxidant activities (TAA%) of the essential oils from wood (82 ± 2.12%), and bark (85 ± 1.24%) were higher than that of tannic acid (81 ± 1.02%), and the TAA% from the essential oil of needles (50 ± 2.24%) was lower than that of tannic acid.
