Teucrium royleanum Wall ex. Benth. and T. quadrifarium Buch.-Ham., growing wild in the Central Himalayan region of Uttarakhand (India), yielded, on steam distillation, 0.07% and 0.09%, respectively of essential oil. The oil samples were analyzed by GC and GC-MS. By GC, both oil samples showed remarkable similarity with respect to the major peaks. Fifty-seven constituents were identified in both the oils representing 96.0% and 96.6% of the total, respectively. The oils were rich in sesquiterpene hydrocarbons (~76.0%). β-Caryophyllene (23.6% and 38.3%), germacrene D (28.9% and 9.4%), α-humulene (5.7% and 5.9%), linalool (4.8% and 1.5%), and 1-octen-3-ol (8.5% and 0.7%) were common to both oils and were the principal constituents. The genus can be classified into two groups on the basis of the present and previous reports on the essential oil composition and chemical markers.

In order to characterize the essential oils of leaves and inflorescences, water distilled volatile oils of hydroponically grown Ocimum basilicum L. were analyzed by GC/EI-MS. Fifty components were identified in the inflorescence and leaf essential oils of the basil plants, accounting for 98.8 % and 99.9 % of the total quantified components respectively. Phenylpropanoids (37.7 % for the inflorescence vs. 58.3 % for the leaves) were the predominant class of oil constituents, followed by sesquiterpenes (33.3 % vs. 19.4 %) and monoterpenes (27.7 % vs. 22.1 %). Of the monoterpenoid compounds, oxygenated monoterpenes (25.2 % vs. 18.9 %) were the main subclass. Sesquiterpene hydrocarbons (25 % vs. 15.9 %) possessed the main subclass of sesquiterpenoidal compounds as well. Methyl chavicol, a phenylpropane derivative, (37.2 % vs. 56.7 %) was the principle component of both organ oils, with up to 38 % and 57 % of the total identified components of the inflorescence and leaf essential oils, respectively. Linalool (21.1 % vs. 13.1 %) was the second common major component followed by ?-cadinol (6.1 % vs. 3 %), germacrene D (6.1 % vs. 2.7 %) and 1,8-cineole (2.4 % vs. 3.5 %). There were significant quantitative but very small qualitative differences between the two oils. In total, considering the previous reports, it seems that essential oil composition of hydroponically grown O. basilicum L. had volatile constituents comparable with field grown counterparts, probably with potential applicability in the pharmaceutical and food industries.

The essential oils from the different parts [inflorescences (E.a.I), stems + leaves (E.a.SL) and roots (E.a.R)] of E. aquifolium Cav. gathered in Cádiz (Spain), have been extracted by steam distillation and analyzed by gas chromatography and gas chromatography coupled to mass spectrometry. Quantitative and qualitative differences have been found between the analyzed plant parts. A total of 107 compounds have been identified. The main constituents were germacrene D (30.3%) and sesquicineole (26.7%) for E.a.I fraction, germacrene D (46.0%) and myrcene (13.8%) in the E.a.SL, while E.a.R showed phyllocladene isomer (63.6%) as a unique major compound. The percentage composition of the other constituents was lower than 5.5% in all the analyzed fractions. In agreement with other Eryngium species, no specific compound could be used as a marker for the chemotaxonomy of E. aquifolium. However, similarities in volatile composition were found between E. aquifolium and other species growing under similar environmental conditions. As far as we know, this is the first report on the essential oil of this species.

Essential oils obtained by hydrodistillation of leaves of two Nigerian species were analyzed for their constituents by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The leaf oil of Ficus benjamina L. (Moraceae), collected during the day, contained high contents of α-pinene (13.9%), abietadiene (9.7%), cis-α-bisabolene (8.2%) and germacrene-D-4-ol (8.4%), while the night sample was dominated by germacrene-D-4-ol (31.5%), 1,10-di- epi-cubenol (8.8%) and hexahydrofarnesylacetone (8.3%). This could be a possible indication of differences in emissions of volatiles by F. benjamina during the day and night. The main compounds of Irvingia barteri Hook. f. (Irvingiaceae) were β-caryophyllene (17.0%), (E)-α-ionone (10.0%), geranial (7.6%), (E)-β-ionone (6.6%) and β-gurjunene (5.1%).

Mechanical damage, during grafting, results in the formation of reactive oxygen species, which are neutralized by the enzymatic and non-enzymatic antioxidant systems which may influence the essential oil composition of grafts and rootstocks because of the formation of oxygenated terpenes, substances with higher reactivity against pathogens. Various studies have demonstrated the biological activity of Annonaceae and the important pharmacological potential of the substances produced by the genus Annona. Thus, we studied the essential oils of leaves collected from the graft (Annona × atemoya) and lateral budding from the rootstock (Annona emarginata), in the same individual, in order to characterize chemical profile. The extraction was carried out by hydrodistillation and separation, quantification and identification of the substances were performed by gas chromatography coupled to a mass spectrometer. Chemical profiles of essential oils were evaluated by principal component analysis (PCA). Annona × atemoya and Annona emarginata presented chemical profiles of essential oil with specific substances. Some substances are common in oils of both species. Germacrene D is predominant in Annona × atemoya and α and β-selinene, β-elemene and spathulenol occurred in Annona emarginata. Our results suggest that the profile of such essential oil may be another indicator for the success of the combination of these two species.

Essential oil composition, antimicrobial activity and flavonoid contents of leaf-fruits of Cedrus libani and Pinus nigra subsp. pallasiana were determined with GC-MS, disc diffusion method and HPLC in three different period. When the essential oil composition of leaf and fruits of P. nigra ssp pallasiana collected in April, July and September, major components were α-pinene, β-pinene, limonene, β-caryophyllene ve germacrene-D. On the other hand, additionally to these contents, myrcene and α–terpineol were also detected in C. libani. According to HPLC analysis, rutin, quercetin, kaempferol, naringin and resveratrol flavonoids were detected in different proportions. While rutin (154.33 µg g-) and resveratrol (20.02 µg g-) has the highest ratio in C. libani, quercetin (9.65 µg g-) and naringin (9.31 µg g-) were detected in P. nigra subsp. pallasiana along with rutin (39.66 µg g-). According to the antimicrobial activity results the essential oils of C. libani obtained in April has produced higher activity than that of July and September. On the contrary, the essential oils from P. nigra subsp. pallasina have produced the best antimicrobial activity on September compared to April and July. As a result, C. libani and P. nigra subsp. pallasiana essential oils have a composition showing antimicrobial activity and their harvesting season should be determined for the best and effective content.

Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.
