“…Regardless of how the pine twigs were treated, α-pinene, β-pinene, β-myrcene, limonene, and β-phellandrene were the major monoterpenes. The components (E)-β-caryophyllene and germacrene D were the predominating sesquiterpenes, confirming former studies [30][31][32][33] . Macchioni et al 30 analyzed essential oils from needles, branches without needles, and cones of P. nigra separately.…”

“…The main components were α-pinene (25.3%), limonene (22.6%), sabinene (12.8%), α-terpineol (8.3%), β-pinene (4.8%), and terpinolene (4.5%). Many terpenoid compounds are typical constituents of conifer resin, and have been reported from P. nigra foliage before [30][31][32][33] . Regardless of how the pine twigs were treated, α-pinene, β-pinene, β-myrcene, limonene, and β-phellandrene were the major monoterpenes.…”

“…Fresh Pinus resin is made mainly of non-oxidized abietanes and a smaller portion of pimaranes the exact amount of each varying depending on the specie [47][48][49][50][51][52][53]. This can be observed in the infrared spectra displayed in Fig.…”

Resins obtained from Pinus genus species have been widely used in very different fields throughout history. As soon as they are secreted molecular changes start altering their chemical, mechanical and optical properties. The ageing processes are complex and chemical and structural changes associated to resin degradation are not yet fully known. Many questions still remain open, for instance changes happening in pimaranes, one of the two diterpenoid constituents of the resin.A systematic study of the ageing process of Pinus resins is done through of Fourier Transform Infrared Spectroscopy (FTIR) using chemical standards and complementing obtained results with Gas Chromatography coupled to Mass Spectrometry (GC/MS) analysis when necessary. Moreover, long-term degradation processes are also investigated through the analysis of a selection of dated historical resins. The study overcomes the limitations of GC/MS and brings new information about the reactions and interactions between molecules during Pinus resin ageing process, providing information about bonds affected and unaffected and can be used as specific markers of the degradation and of the resins themselves.

“…Methyl chavicol has been identified in the resin of pines (Pinus spp.) (Mirov, 1961;Salom and Hobson, 1995 and references therein), such as Caribbean (Snyder and Bower, 2005), black (Rezzi et al, 2001), Scots, slash (Chadwick and Palkin, 1941), longleaf (Mirov, 1948), lodgepole, loblolly (Strom et al, 2002;Werner, 1972), and ponderosa (e.g. Cobb et al, 1972;Adams and Edmunds Jr., 1989).…”

Abstract. We report measurements of ambient atmospheric mixing ratios for methyl chavicol and determine its biogenic emission rate. Methyl chavicol, a biogenic oxygenated aromatic compound, is abundant within and above Blodgett Forest, a ponderosa pine forest in the Sierra Nevada Mountains of California. Methyl chavicol was detected simultaneously by three in-situ instruments -a gas chromatograph with mass spectrometer detector (GC-MS), a proton transfer reaction mass spectrometer (PTR-MS), and a thermal desorption aerosol GC-MS (TAG) -and found to be abundant within and above Blodgett Forest. Methyl chavicol atmospheric mixing ratios are strongly correlated with 2-methyl-3-buten-2-ol (MBO), a light-and temperature-dependent biogenic emission from the ponderosa pine trees at Blodgett Forest. Scaling from this correlation, methyl chavicol emissions account for 4-68% of the carbon mass emitted as MBO in the daytime, depending on the season. From this relationship, we estimate a daytime basal emission rate of 0.72-10.2 µgCg −1 h −1 , depending on needle age and seasonality. We also present the first observations of its oxidation products (4-methoxybenzaldehyde and 4-methyoxy benzene acetaldehyde) in the ambient atmosphere. Methyl chavicol is a major essential oil component of many plant species. This work suggests that methyl chavicol plays a significant role in the atmospheric chemistry of Blodgett Forest, and potentially other sites, and should be included explicitly in both biogenic volatile organic carbon emission and atmospheric chemistry models.
