Salvia lavandulifolia (Spanish sage, Lamiaceae) is widely cultivated in the Mediterranean region and used for the flavor and food industry, perfumery and medicinal purposes. The essential oil, which is responsible for the specific flavor, is produced and stored in specialized epidermal oil glands. In S. lavandulifolia peltate essential oil glands occur on all aerial parts of the plant. The content of single oil glands from different positions on the plant (leaf, calyx, corolla and anther) were directly sampled using a solid-phase micro-extraction (SPME) fiber and analyzed by GC/FID and GC/MS in order to study the variability of the essential oil composition. It was found that the composition of terpenoids is quite variable within a plant. The leaves and calyces are characterized by the main compounds, 1,8-cineole, camphor and β-pinene, and by the sesquiterpenes α-humulene and β-caryophyllene. The corolla shows the highest proportion of borneol, but a low concentration of camphor. In the essential oil of the anthers the percentages of limonene, β-pinene and the diterpene manool are by far higher than in all other plant parts, whereas the proportions of camphor and the sesquiterpenes are considerably lower.

Abstract- The essential oil composition from the aerial parts of Ormenis africana (Asteraceae), an endemic species from Morocco, has been investigated by GC/MS. A total of 31 compounds were identified, representing 77%. After fractionation by column chromatography, the main compound was isolated and its structure elucidated by NMR spectroscopy. The essential oil was dominated by oxygenated compounds with spathulenol (45.8%) followed by camphor (7.1%), -cadinol (5.9%) and -bisabolol (5.9%) as the main compounds. This oil can be classified as spathulenol-type according to its spathulenol content. In vitro the antibacterial activity of the whole essential oil against three Gram positive (Bacillus cereus, Enterococcus faecalis, Streptococcus C) bacteria and three Gram negative (Proteus vulgaris, Escherichia coli, Pseudomonas aeroginosa) bacteria, showed significant results.

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.

Variations in the essential oil composition of aerial parts of pineapple weed (Chamomilla suaveolens (Pursh) Rydb.) growing wild in Estonia, were determined using GC/FID and GC/MS. Forty-four components were identified, representing over 90% of the total oil. Nine compounds have not been mentioned in the literature before. The principal biologically active compounds in C. suaveolens oils were (Z)-en-yne-dicycloether (17.0 – 40.7%), (E)-β-farnesene (19.5– 32.2%), geranyl isovaleriate (8.4 –18.4%), palmitic acid (0.3 – 9.4%) and myrcene (1.1 – 7.9%). The investigation seems to approve the benefit of using aerial parts of pineapple weed as the substitute for flowers.

Leaf Essential Oil

The essential oils from fresh aerial parts of Monticalia greenmaniana (Hieron) C. Jeffrey (Asteraceae) collected in March, were analyzed by GC/MS. Oil yields (w/v) of 0.1% (flowers), 0.07%, (stems) and 0.1% (leaves) were obtained by hydrodistillation. Thirteen, sixteen and eighteen components, respectively, were identified by comparison of their mass spectra with those in the Wiley GC-MS Library data base. The major components of the flower and stem oils were 1-nonane (38.8% flowers; 33.5% stems), α-pinene (29.0% flowers; 14.8% stems) and germacrene D (15.6% flowers; 18.6% stems). However, in the leaf oil, germacrene D was observed at 50.7%, followed by β-cedrene at 8.4 %. The leaf essential oil showed a broad spectrum of antibacterial activity against the important human pathogenic Gram-positive and Gram-negative bacteria Staphylococcus aureus (ATCC 25923), Enterococcus faecalis (ATCC 19433), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853) and Klebsiella pneumoniae (ATCC 25955) with MIC values ranging from 75 to 6000 ppm.
