“…All four species contain α-pinene, ranging from 3.8 % to 15.6 %, while terpinolene is found in concentrations ranging from 0.1 % to 6.9 %. It should be noted that Pistacia terebinthus is characterized by an elevated concentration of limonene (34.2 %) [22], Pistacia atlantica is characterized by an elevated concentration of bornyl acetate (21.5 %) [23], Pistacia lentiscus contained as major components myrcene (68.2-71.0 %) and limonene (9.6-19.7 %) [24] and Pistacia palaestina is characterized by an elevated concentration of (E)-ocimene (41.3 %) and sabinene (20.3 %) [25]. All the major components of the related species are found in P. vera in concentrations amounting to less than 2.5 %.…”

“…GC-MS analyses were also performed on a Finnigan Trace GC-MS with an external ion source in both the EI and chemical ionization (CI) modes at a flow rate of 1.0 mL/min, using CH 4 as the CI ionization reagent. The identification of the compounds (Table 1) was based on comparison of their retention indices (RI), obtained using n-alkanes (C 8 -C 25 ), and comparison of their EI-mass spectra with the NIST/NBSWiley library spectra and literature data [26]. Additionally, the identity of all compounds was confirmed by comparison of the expected molecular weights with the results obtained from the CI spectra and in several cases by co-injection with available authentic samples.…”

Abstract:The essential oils of the fruits and the leaves of pistachio (Pistacia vera L.) were analyzed by GC and GC/MS. Fresh unripe pistachio fruits were richer in essential oil (0.5 %, w/w) than the leaves (0.1 %, w/w). Twenty one compounds were identified in the essential oil of the fruits and the major components were (+)-α-pinene (54.6 %) and terpinolene (31.2 %). The enantiomeric ratio of the major constituents of the essential oil of the fruits was determined using chiral GC/MS and it was found that the (+)/(-)-α-pinene ratio was 99.5:0.5, (+)/(-)-limonene 80:20, (+)/(-)-β-pinene 96:4, and (+)/(-)-α-terpineol 0:100. Thirty three compounds were identified in the essential oil of the leaves and the major components were found to be α-pinene (30.0 %), terpinolene (17.6 %) and bornyl acetate (11.3 %).

“…In the essential oil of unripe fruits from P. terebinthus of Turkish origin, limonene (34.2%), α-pinene (15.6%) and β-pinene (11.5%) were reported as the major constituents, 14 while in P. atlantica myrcene, sabinene and terpinen-4-ol were detected as the main compounds. In a recent study, Flamini et al 15 reported on the chemical composition of P. palaestina (closely related to P. terebinthus, and considered by some botanists as a subspecies or variety of it); the main compounds in the leaf oil were α-pinene (63.1%) and myrcene (13.3%) and in unripe fruit oil (E)-ocimene (41.3%) and sabinene (20.3%). The vast amount of literature deals with the chemical composition of P. lentiscus essential oils, where a considerable variability in the terpene composition is also observed.…”

The essential oils of leaves (from male and female plants), unripe fruits and leaf-buds of different samples of Pistacia atlantica collected from Greek East Aegean islands (Kalimnos and Lesvos) were analysed by GC-MS and GC. Qualitative and quantitative differences among the samples and different organs of the plant were observed. The oils were rich in monoterpenes. The main components in the leaf oil from the female plants were myrcene (17.8%, 24.8%) and terpinen-4-ol (11.6%, 6.0%) in the Kalimnos and Lesvos samples, respectively, while in the leaf oil from the male plants terpinen-4-ol (17.3% Kalimnos) and p-mentha-1(7),8-diene (41.1%, Lesvos) were the dominant constituents. The major components in unripe fruits were terpinen-4-ol (25.7%, 8.9%), myrcene (20.2%, 34.5%) and sabinene (14.9%, 19.5%). In the leaf-buds oils sabinene (52.1%) and α α α α α-pinene (11.6%) were the main constituents in the Kalimnos sample, while in the Lesvos sample the major constituent was p-mentha-1(7),8-diene (42.4%).

“…This kind of herbivore spends a major part of its life cycle into the plant tissues 10 and apparently do not have behavioral strategies to avoid the effects of the plant defensive metabolites. Among a few published works related to signaling between insect gall makers and their hosts, Flamini and coworkers 11 reported changes in volatile composition of Pistacia palaestina Boiss (Anacardiaceae) under the attack of Baizongia pistaciae (Homoptera: Aphidoidea).…”

Baccharis spicata (Asteraceae) e Schinus polygamus (Anacardiaceae) são plantas nativas do Rio Grande do Sul e são hospedeiras de dois psilídeos galhadores (Hemiptera, Psyllidae) ainda não identificados. As duas plantas em estudo produzem óleo essencial e seus compostos voláteis podem ter um importante papel na interação inseto-planta. A extração e análise dos voláteis das folhas, folhas galhadas e galhas foram realizadas por microextração em fase sólida no modo "headspace" e por cromatografia gasosa com detector de espectrometria de massas. Verificou-se que a composição do "headspace" das galhas de B. spicata e S. polygamus é diferente daquela do "headspace" das folhas sadias. A principal alteração observada foi o aumento da contribuição de monoterpenos no "headspace" das galhas comparativamente ao que se verificou nos tecidos saudáveis. Algumas mudanças também foram observadas na produção de voláteis verdes, em ambas as espécies, mas especialmente na S. polygamus. O possível papel ecológico desses compostos químicos também é discutido.Baccharis spicata (Asteraceae) and Schinus polygamus (Anacardiaceae) are plants native from Rio Grande do Sul and are hosts of two unidentified galling psyllids (Hemiptera, Psyllidae). Both plant species produce essential oil and their volatile compounds play an important role related to this kind of plant-insect interaction. Extraction and analysis of volatiles produced by leaves, galled leaves and galls were performed using headspace solid phase microextraction and gas chromatography coupled to mass spectrometry detector. Composition of the headspace of B. spicata and S. polygamus galls showed a significant change in their volatile profile when compared to healthy leaves. These changes were mainly related to a higher production of monoterpenes in galled tissue, compared to what was found in healthy samples. Some changes on the production of green leaf volatiles were also observed in both plant species, especially in S. polygamus. The possible ecological role of these chemical changes was discussed. Keywords: galls, leaves, Baccharis spicata, Schinus polygamus, headspace solid phase microextraction IntroductionGalls are the result of histological alterations in plant organs, mainly hypertrophy and hyperplasy, caused by the activity of an inductor which can be virus, bacteria, nematodes, insects and other plants. These organisms can interfere with the normal development of cells and tissues leading to several physiological and morphological changes. Gall-inducing insects (insect gallmakers) are masters in the art of beguiling or compelling the host plant to provide food and shelter with a minimum expenditure of effort on their part and galls induced by insect are one of most diverse plant galls.1 Galls are found on all plant organs, such as flowers, leaves, stems and roots. They provide food and shelter to the inducer which lives in a microenvironment relatively safe from natural enemies.2 The leaf galls are variable in form and occur in the majority of plant hosts. 2Plant volatil...
