In the current study the essential oil obtained from the leaves of Eucalyptus camaldulensis plants collected from five localities of the Montenegro coastline was analyzed. The oil yield varied from 0.63 % (Kotor) up to 1.59% (Tivat). The chemical composition of the leaf essential oil was analyzed using GC-MS technique. Monoterpene hydrocarbons were a major class of compounds. Among them, dominant compounds were p-cymene (17.38-28.60%), ?-phellandrene (12.35-14.47%) and ?-pinene (0.94-11.48%). The second largest group was oxygenated monoterpenes with cryptone (4.97-7.25) and terpinene-4-ol (2.75-4.21%) as predominant. Besides high content of sesquiterpene alcohol spathulenol (7.83-14.15%) was found. According to the results obtained E. camaldulensis from Montenegro can be classified in the chemotype with low 1,8-cineole and high p-cymene and cryptone ratio.

The principal aim of this study was to analyze the chemical composition and qualitative and quantitative variability of essential oils obtained from seven naturally grown populations of thePinus peuceGrisebach, Pinaceae in Kosovo. Plant materials were collected from three populations in the Sharri National Park and from four other populations in the Bjeshkët e Nemuna National Park, in Kosovo. Essential oils were obtained by steam distillation and analyzed by GC-FID (Gas Chromatography-Flame Ionization Detection) and GC-MS (Gas Chromatography-Mass Spectrometry). The results showed that the yield of essential oils (v/wdry weight) varied depending on the origin of population and the plant organs and ranged from 0.7 to 3.3%. In total, 51 compounds were identified. The main compounds wereα-pinene (needles: 21.6–34.9%; twigs: 11.0–24%),β-phellandrene (needles: 4.1–27.7; twigs: 29.0–49.8%), andβ-pinene (needles: 10.0–16.1; twigs: 6.9–20.7%). HCA (Hierarchical Cluster Analysis) and PCA (Principal Component Analyses) were used to assess geographical variations in essential oil composition. Statistical analysis showed that the analyzed populations are grouped in three main clusters which seem to reflect microclimatic conditions on the chemical composition of the essential oils.

The fruits of Zanthoxylum leprieurii Guill. & Perr. (Rutaceae) are traditionally used in Africa, particularly in Cameroon, as a spice and in the treatment of sickle cell anaemia. The objective of this study was to investigate the fruit essential oils from different sample locations and during their maturation period by using GC and GC-MS. Except for one sample collected in Aniak which consisted mainly of oxygenated monoterpenes, the volatile composition of Z. leprieurii fruits exhibited relative high amounts of monoterpene hydrocarbons (61.1-90.9%) such as (E)-β-ocimene (13.4-75.2%) and a-pinene (1.1-40.7%). The influence of the maturity stage on the chemical composition of the essential oils has resulted in an increase of oil yield and variations in the content of volatile compounds (a-pinene 13.3-75.6; (E)-β-ocimene 2.9-64.0%). Keywords: Senegal, Zanthoxylum leprieurii fruits, essential oil, chemical variability, stage of maturity and GC-MS.

The chemical composition and antimicrobial activity of the essential oils obtained from the flowering aerial parts and ripe fruits of Echinophora spinosa L. (Apiaceae) from central Italy were analyzed by GC/MS. The major constituents of the oil from the aerial parts were β-phellandrene (34.7%), myristicin (16.5%), δ3-carene (12.6%), α-pinene (6.7%) and α-phellandrene (6.2%), and of the oil from the ripe fruits p-cymene (50.2%), myristicin (15.3%), α-pinene (15.1%) and α-phellandrene (8.1%). The two oils showed good antimicrobial activity against Clostridium difficile, C perfringens, Enterococcus faecalis, Eubacterium limosum, Peptostreptococcus anaerobius and Candida albicans with MIC values respectively of 0.25, 0.25, 0.25, 0.25, 2.25, and 0.50%, v/v, and 0.13, 0.13, 0.13, 0.13, 2.25, 0.50%, v/v, for aerial parts and ripe fruits respectively. A less significant antimicrobial activity against bifidobacteria and lactobacilli, very important in the intestinal microflora, was also detected, with MIC values higher than 4.0%, v/v.

The essential oil composition of the leaves, stem, flowers and roots of Ligusticopsis wallichiana (DC.) Pimenov & Kljuykov were analyzed by GC-FID and GC-MS methods. Forty-five constituents, forming 93.2%–97.8% of the oil compositions, were dominated by acetylenic (31.5%–92.8%) compounds and sesquiterpenoids (0.3%–44.4%). The leaf essential oil was mainly composed 3,5-nonadiyne (35.8%), β-selinene (20.9%), α-funebrene (10.1%) and ( Z)-falcarinol (6.1%). The stem oil was dominated by acetylenic compounds (73.8%) represented by 3,5-nonadiyne (67.8%) and ( Z)-falcarinol (5.7%). On the contrary, the major components of the flower essential oil were sesquiterpenoids (37.5%), such as germacrene D (16.6%), α-funebrene (7.4%), and acetylenic compounds (31.5%), such as ( Z)-falcarinol (21.0%) and 3,5-nonadiyne (10.0%). Monoterpenoids constituted 23.9% of the flower oil with limonene (19.9%) as the single major constituent. The essential oil of the roots was dominated by 3,5-nonadiyne (90.5%). The results showed considerable qualitative and quantitative variations in the essential oil compositions of the different plant parts of L. wallichiana. ( Z)-Falcarinol (1.9%–21.0%) and α-funebrene (0.1%–10.1%) were reported for the first time from the essential oils of L. wallichiana.

AbstractDifferences in essential oil composition of wild Achillea millefolium L., collected at five habitats in Lithuania, where plants with pink (f. rosea) and white (f. millefolium) flowers grow together, were reported. For the first time, oils of different plant organs (inflorescences and leaves) of both forms from every population were analysed in detail. Chemical analysis was performed by GC and GC-MS. The most predominant constituents of the oils were nerolidol (9.4–31.9%, in 11 out of 20 samples), caryophyllene oxide (8.4–23.0%, 4 leaf oils), ß-pinene (8.0–15.2%, 2 samples), eudesmol (11.8–15.8%, 2 leaf oils) and 1,8-cineole (11.9%, one inflorescence oil). Domination of nerolidol was mostly characteristic of A. millefolium f. rosea essential oils (in 8 out of 10 oils). The inflorescences biosynthesised markedly larger amounts of nerolidol and ß-pinene than those of the leaves. An opposite correlation was observed for caryophyllene oxide and eudesmol. Chamazulene (≤2.7%) was determined only in six oils. The 65 identified constituents made up 75.4–96.5% of the oils.

The herbal material of <em>Coriandrum sativum </em>is the fruit. Fresh herb is also used as an aromatic spice. The aim of the present study was to evaluate the content and chemical composition of coriander herb obtained at different plant growth stages. Coriander plants were grown in a glasshouse, the herb was harvested at the initial stage of flowering and from regrowing shoots. Essential oil extraction from the herb was performed by the hydrodistillation method, whereas the assessment of the chemical composition – using GC-MS method. The examined material contained 0.17–0.29 ml × 100g<sup>-1</sup> of essential oil, depending on the stage of plant development when the harvest was done. 61 (generative phase) and 65 (vegetative phase) compounds were found in the examined coriander oil. The essential oil from the coriander herb contained the highest amount of aliphatic aldehydes, among which was decanal, <em>E</em>-2-dodecanol and <em>E</em>-2-decenol had the highest percentages. The contents of most aliphatic aldehydes decreased with each subsequent harvest of the herb. In addition to the above-mentioned aliphatic aldehydes, the presence of linalool, phytol, and oleic acid was found in the essential oil extracted from the coriander herb.

In previous work [1], the essential oil of the aerial parts of Marrubium vulgare L. obtained by hydrodistillation was analysed by gas chromatography coupled to mass spectrometry (GC-MS) in order to determine their chemical composition. Fifty (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97 %), Germacrene D-4-ol (9.61 %), α- pinéne (9.37 %), Phytol (4.87 %), Dehydro-sabina ketone (4.12 %), Piperitone (3.27 %), δ-Cadinene (3.13 %), 1-Octen-3-ol (2.35 %) and Benzaldehyde (2.31 %). In this study, the antioxidant properties of essential oil were examined. The results showed that this oil can be considered an effective source of antioxidants of natural origin. This is the first report on chemical composition of M. vulgare essential oil cultivated in Algeria and the original study on the antioxidant activity of M. vulgare essential oil. The antioxidant activity was investigated with one method: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method.
