The chemical composition of the hydrodistilled essential oils of four Salvia spp. were analysed by GCMS. Three of them (Salvia aramiensis Rech. fil., Salvia fruticosa Mill., Salvia tomentosa Mill.) analyzed in this study grow naturally in the Hatay flora. On the other hand, S. aramiensis is an endemic plant in Hatay flora. Fourth species (Salvia officinalis L.) is not growing in the flora of Turkey, but is only cultivated. The highest essential oil content (5.31%) was found in S. aramiensis and the least 1.68% was detected in S. officinalis. Eucalyptol was the main constituent for S. aramiensis, S. fruticosa and S. tomentosa. While this component was 58.65% in S. aramiensis, it was determined as 44.70 and 34.97% in S. tomentosa and S. fruticosa, respectively. In S. officinalis, the main constituent was determined as δ-Thujone (33.83%) and camphor (21.46%). Eucalyptol has been identified as the main composition in sage species which is grown in flora.

Abstract The aim of the studies conducted in 2012-2013 was to compare the chemical composition of essential oils isolated from wild thyme (Thymus serpyllum L.) by hydrodistillation in Deryng and Clevenger apparatus. GC-MS analysis of the isolated oils revealed that carvacrol (42.81-45.24%), γ-terpinene (7.68-9.04%), β-caryophyllene (5.28-9.10%), β-bisabolene (5.76-6.91%) and carvacrol methyl ether (4.92-6.09%) were the major components of all the samples. On the basis of the obtained data it was proved that the type of distillation apparatus had no significant effect on the content of the main essential oil constituents of wild thyme. However, based on the means for both years of the study it was proved that hydrodistillation in Deryng apparatus was more effective for carvacrol concentration, while in Clevenger apparatus - for y-terpinene and carvacrol methyl ether concentration. The type of distillation apparatus had no significant effect on the content of the other essential oil constituents.

ABSTRACT: Campomanesia adamantium is a native fruit species of the Cerrado and is used in food and medicines and as bee pasture. The chemical composition of essential oils obtained from plants of the same species have varying constituent proportions due to the influence of extractive factors, environmental, genetic and ontogenetic. This study aimed to identify the influence of hydrodistillation time on the content and chemical composition of essential oil extracted from the leaves of C. adamantium . Treatments consisted of five extraction times (1, 2, 3, 4, and 5h) using Clevenger with five replications in a completely randomized design. It was observed that after two hours of hydrodistillation, the essential oil content remains constant. Regarding the chemical constituents of essential oil, variation of the proportions of the compounds tested occurred at all hydrodistillation times. The compounds spathulenol oxygenated sesquiterpenes and caryophyllene oxide were the majority in the five hydrodistillation times.

Detailed GC and GC/MS analyses of essential-oil samples obtained by hydrodistillation of Morus alba L. and M. nigra L. leaves (four samples) allowed the identification of 131 constituents representing 95.1 – 96.4% of the total GC peak areas. The most abundant compounds classes were alkanes, diterpenoids, carotenoid-derived compounds and fatty acid-related constituents with trans-phytol (7.9 – 71.2%), ( E,E)-geranyl linalool (0.2 – 8.0%), ( Z)-bovolide (8.1%) and n-chain alkanes (in total, 17.5 – 52.4%) as the major constituents of the analyzed samples. In general, there were only quantitative differences noted between M. nigra essential oils from fresh and dry leaves. The most discernable changes included a variation in the content of the major constituents (e.g. the relative amount of trans-phytol and the total amount of alkanes decreased by 5.8% and ≈ 2%, respectively, while that of ( E,E)-geranyl linalool increased by 7.8%). On the other hand, the composition of M. alba essential oil was much more significantly affected by the drying process. The highest quantitative differences were noted for trans-phytol, geranyl acetone, and all isomers of 4,6,8-megastigmatrien-3-one. Also, a rare plant metabolite, ( Z)-bovolide, characteristic of leaf senescence, was only identified (8.1%) in the essential oil of M. alba dried leaves.

Neomitranthes obscura(DC.) N. Silveira is an endemic plant of Brazilian Atlantic Forest and widely spread in the sandbanks of “Restinga de Jurubatiba” National Park. It is popularly known by local population as “camboim-de-cachorro” or “cambuí-preto” and recognized by its black ripe fruits. However, specimens with yellow ripe fruits were localized in the “Restinga de Jurubatiba” National Park. The aim of the present study was to evaluate chemical composition of essential oils obtained from leaves and fruits ofN. obscuraspecimens with different fruit color (black and yellow) by GC and GC-MS. Essential oils from leaves of specimens with black and yellow fruits indicated a predominance of sesquiterpenes (81.1% and 84.8%, resp.). Meanwhile, essential oil from black fruits presented a predominance of monoterpenes (50.5%), while essential oil from yellow fruits had sesquiterpenes (39.9%) as major substances. Despite previous studies about this species, including essential oil extraction, to our knowledge this is the first report onN. obscurafruits with different colors. Our results suggest the occurrence of unless two different varieties for this species.

In this study, anti-mildew activities of the essential oils of the leaves, wood, twigs, flowers, and their constituents from Michelia compressa var. formosana were evaluated in vitro against 7 mildew fungi. The main compounds responsible for the anti-mildew activities were isolated and identified. The essential oils from the fresh leaves, wood, twigs, and flowers of M. compressa var. formosana were isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. The essential oil yield from the flowers was the highest, and the oils obtained from the 4 parts of the tree were composed mainly of sesquiterpenoids. The leaf oil consisted primarily of α-cadinol (18.9%) and germacrene D (18.5%); the twig oil's main constituent was α-cadinol (19.1%); the wood oil's major components were α-cadinol (25.7%) and β-eudesmol (20.2%); and the flower oil contained α-cadinol (11.4%). Comparing the anti-mildew activities of the oils suggested that wood oil was the most effective. Further fractionation of the wood oil produced α-cadinol, β-eudesmol, τ-cadinol, and elemol. The 4 compounds exhibit very strong anti-mildew activities, and these in descending order are α-cadinol, elemol, β-eudesmol, and τ-cadinol. For the anti-mildew activities of the wood oil, the active source compounds were determined to be α-cadinol, elemol, β-eudesmol, and τ-cadinol.

The objective of this research was to analyze the chemical composition, antimicrobial and cytotoxic activity of Heracleum pyrenaicum subsp. pollinianum (Bertol.) F. Pedrotti & Pignatti (HPP) and H. orphanidis Boiss. (HO) essential oils. The composition of the oils was analyzed by GC and GC-MS. β-Pinene (35.1%) was the most abundant compound in HPP root oil, while ( Z)-falcarinol (80.0%) dominated in HO root oil. ( E)-Nerolidol (28.5%) was the main constituent in HPP leaf oil. HPP fruit oil, as well as HO leaf and fruit oils mainly contained aliphatic esters, mostly octyl acetate (50.5–84.5%). Antimicrobial screening was performed by microdilution method against eight bacterial and eight fungal strains. The strongest antibacterial activity was shown by both root oils (MICs 0.02–0.60 mg/mL and MBCs 0.04–2.50 mg/mL for HPP, and MICs 0.02–1.25 mg/mL and MBCs 0.04–2.50 mg/mL for HO), while the best antifungal potential was exhibited by HPP fruit oil (MICs 0.30–0.60 mg/mL and MFCs 0.60–1.25 mg/mL) and HO leaf oil (MICs 0.15–0.63 mg/mL and MFCs 0.30–1.25 mg/mL). The tested root and fruit oils exhibited strong cytotoxic effect, which was determined by MTT test against HeLa (IC50 7.53–21.07 μg/mL) and LS174 (IC50 24.16–58.86 μg/mL) cell lines.

The chemical composition and the qualitative and quantitative variability of the essential oils of three taxa belonging to the Teucrium genus were studied. The investigated taxa, that grow wild in Sicily, were Teucrium flavum L. (section Chamaedrys (Mill.) Scheb.), Teucrium montanum and Teucrium capitatum L. of section Polium (Mill.) Scheb. Essential oils were extracted by hydrodistillation and analyzed by GC-MS. In total, 74 compounds were identified. Sesquiterpene hydrocarbons were found to be the main group for T. flavum (48.3%). T. capitatum consisted essentially of monoterpene hydrocarbons (72.7%), with α-pinene (19.9%), β-pinene (27.6%) and sylvestrene (16.6%) as the most abundant compounds whereas ledene oxide (12.1%), epiglobulol (13.5%) and longifolenaldehyde (14.5%) were identified as the main constituents among the oxygenated sesquiterpenes (63.5%) of T. montanum. Furthermore, a complete literature review on the composition of the essential oils of all the other accessions of these Teucrium taxa, studied so far, was performed. Hierarchical Cluster Analysis (HCA) and Principal Component Analyses (PCA) were used in order to demonstrate geographical variations in the composition of the essential oils.
