“…In addition, some short-chain (C 6 -C 12 ) fatty acids were detected. As might be expected, the TMS esters of resin acids eluted in the same order s their methyl esters on a similar column (Foster and Zinkel 1982). Poe and Liesch 1983;Tulloch 1985) further indicated the presence of at least ten minor fatty acids, but they could not be reliably identified, since many of them co-eluted with some other compounds.…”

Gas-liquid chromatography on an SE-54 fused-silica capillary column indicated the presence of more than 200 monomeric compounds in pine kraft black liquor, of which 48 hydroxy monocarboxylic acids, 32 dicarboxylic acids, 14 aromatic carboxylic acids, 24 other aromatic compounds, several fatty and resin acids, and three cyclic enols were identified by mass spectrometry. Mass spectra are reported for the trimethylsilyl derivatives of 2-hydroxy-3-methyl-2-cyclopenten-l-one, 2-hydroxy-3,4-dimethyl-2-cyclopenten-l-one,2,3-dihydroxy-2-cyclopenten-l-one,3-hydroxy-5-methylacetophenone,4hydroxymonocarboxylic acids, 7 resin acids, and 3 -hydroxy-guaiacylalkanoic acids.3,5-Didcoxy-2-C-methylpentonic acid: m/z 349 (M-15

“…Besides comparing the GC/FID standard and sample diterpene retention times to one another and to the relative retention times of Foster and Zinkel (1982), we performed additional analyses on a Hewlett Packard 1090 high-pressure liquid chromatograph with a diode array detector to confirm the identity of the various resin acids (Kersten et al 2006). We injected 20 mL of nonmethylated standard solutions (0.6 mg/mL) of levopimaric, palustric, isopimaric, abietic, dehydroxyabietic, and neoabietic acid and selected cone samples (ground tissue in neat ethanol) on a Vydac C 18 column (7.8 mm 3 250 mm) with a mobile phase consisting of MeOH : 1.7% acetic acid (87.5 : 12.5) run isocratically at 1.0 mL/min with the column heater set at 30°C.…”

We measured the terpenoid chemistry, cone insect distribution, and the relationship between these two parameters in the seed cones of ponderosa pine. Analyses of mono-, sesqui-, and diterpenes from four separate sites revealed high amounts of terpenoid diversity and variation. The majority of this variation occurred among trees within sites, but differences were also seen among sites and among cone clusters from individual trees. Cone insect distributions differed substantially in both time and space, with significant differences seen between two points in time and between five sites. Negative correlations existed between levels of cone insect herbivory and both a monoterpene and a diterpene factor at one site, indicating that these herbivores may be one reason that ponderosa pine maintains the high levels of chemical variation observed.

“…The similarities in the EI mass spectra of each of the paired peaks did not allow more detailed identification. Detailed comparisons of their RIs with those in the literature 23 identified them as methyl esters of 8-isopimaren-18-oic acid (I: CAS# 7715À73À3), 8-pimaren-18-oic acid (II: CAS# 7715À 77À7), 13β(H)-abieten-18-oic acid (III: CAS# 19402À28À9), and 13α(H)-abiet-8-en-18-oic acid (IV: CAS# 17611À16À4). The same set of dihydroresin acids was previously identified in a tire used in the U.S. 21 It is be worth noting that the disproportionated rosin contained hydrogenated resin acids with pimarene/isopimarene skeletons (I and II) but not those with abietene skeletons (III, IV).…”

To propose new molecular markers for tire-wear emissions, four dihydroresin acids, that is, 8-isopimaren-18-oic acid (I), 8-pimaren-18-oic acid (II), 13β(H)-abieten-18-oic acid (III), and 13α(H)-abiet-8-en-18-oic acid (IV), were identified and investigated for source specificities, distributions, and environmental stabilities. The absence of I-IV in natural sources and the linear correlations between dihydroresin acids with different skeletons in tires and in environmental samples demonstrated that I-IV are specific markers for synthetic rubbers. The ratio of III + IV to the sum of III + IV plus abietic acid showed the resin acids distribution between different environmental compartments receiving contributions from traffic and natural sources. The physicochemical properties and results of photolysis experiments suggested that I-IV can set lower limits for tire-wear contributions to environmental loads of particulate matter (PM) and polycyclic aromatic hydrocarbons with molecular weight ≥202. By comparing III + IV concentrations or (III+IV)/pyrene or (III+IV)/benzo[a]pyrene ratios in tires and those in environmental matrices, the contributions of tire-wear emissions to PM, pyrene, and benzo[a]pyrene were estimated to be 0.68 ± 0.54%, 6.9 ± 4.8%, and 0.37 ± 0.18% in roadside PM and 0.83 ± 0.21%, 0.88 ± 0.52%, and 0.08 ± 0.06% in rooftop PM.
