The essential oil of the aerial parts of Fumana thymifolia was investigated by GC-MS. Thirty-eight components were identified in the oil representing 89.5%. The major compounds were pulegone (19.8%) and nonanal (9.5%). © 2001, Taylor & Francis Group, LLC. All rights reserved

Essential Oil of Calamintha nepeta subsp. glandulosa from Greece

The essential oil of spontaneous plants of Calamintha nepeta (L.) Savi subsp. glandulosa (Req.) P.W. Ball with mint-like character were investigated by GC/MS. Twenty three components were identified in the oil representing 99.7%. The major compounds were pulegone (41.0%), menthone (32.0%), piperitone (7.3%) and piperitenone (7.0%). © 2001, Taylor & Francis Group, LLC. All rights reserved

Chemical composition of alkanna orientalis from Greece

The chemical composition of fresh aerial parts oil of alkanna orientalis (l.) boiss. Was examined by gc and gc/ms. Twenty-eight components were identified representing 98.1% of the total oil. The main components were β-eudesmol (36.9%), α-eudesmol (16.3%) and γ-eudesmol (14.1%). © 2008, Taylor & Francis Group, LLC. All rights reserved

Chemical composition of the essential oil of Achillea umbellata growing in Greece

The essential oil of the aerial parts of the endemic Achillea umbellata (Compositae) was obtained by hydrodistillation and analysed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC-MS). Sixty-six constituents were identified. The major constituents of the oil were β-thujone (62.8%) and camphor (8.7%)

Chemotaxonomic significance of volatile compounds in Thymus samius and its related species Thymus atticus and Thymus parnassicus

Thymus samius, a rare species endemic to the island of Samos (East Aegean, Greece), has been considered to be of possible hybrid origin, with Thymus cilicicus, Thymus parnassicus or Thymus zygioides as putative parents. Morphologically it also resembles Thymus atticus. In order to evaluate any possible chemotaxonomic relationships indicated by the qualitative and/or quantitative differentiation of volatile compounds, the essential oils of T. samius, T. parnassicus and T. atticus were analyzed and the oils of T. cilicicus and T. zygioides were used for comparison. T. atticus presents considerable variation in chemical constituents, with all Greek populations being poor in thymol/carvacrol and rich in (E)-nerolidol, germacrene D, (E)-caryophyllene, caryophyllene oxide, 1,8-cineole, α-pinene and camphene, depending on the sample. T. parnassicus shows remarkable qualitative stability in its volatile constituents, and all its populations have a similar profile with (E)-caryophyllene being the most prominent compound. T. samius is characterized by the presence of germacrene D and β-bisabolene, which constitute almost half its oil percentage. This species is also characterized by a low amount of monoterpenes; the latter exist in a considerable percentage in the related species. Our results indicate that T. samius does not show similarity or intermediacy in chemical compounds with any given couple of T. atticus, T. parnassicus, T. cilicicus, or T. zygioides. © 2005 Elsevier Ltd.

Composition and antibacterial activity of the essential oil of Satureja parnassica subsp. parnassica

The essential oils of Satureja parnassica subsp. parnassica (samples A and B), were analyzed by means of GC/MS. From the fifty-seven identified constituents representing 98.5% and 99.35% of the oils respectively, (E)-caryophyllene, carvacrol and caryophyllene oxide were the major components of sample A (flowering stage), whereas in sample B (vegetative stage) major components were spathulenol, p-cymene and linalool. The oils were tested against Helicobacter pylori (HP), as well as against six aerobically growing bacteria. Both samples showed a moderate activity against Gram-positive bacteria; Sample A oil showed greater anti-HP activity than sample B

Volatile metabolites of Pistacia atlantica Desf. from Greece

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-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%).

Essential oil from the flowers and leaves of cassia fistula L.

The chemical compositions of the fower and leaf essential oil of Cassia fistula L. were examined by GC and GC/MS. Forty-four compounds were identified representing 92.6% and 90.7% of the fower and leaf oil, respectively. The main components of the flower oil were (E)-nerolidol (38.0%), and 2-hexadecanone (17.0%), while the leaf oil consisted mainly of phytol (16.1%). © 2007, Taylor & Francis Group, LLC.
