Titre : Aromatic plants of northwest Argentina. Constituents of the essential oils of aerial parts of seven Verbenaceae : Lantana and Aloysia. Type de document : texte imprimé Auteurs : José S. Dambolena, Auteur ; Maria P. Zunino, Auteur ; Enrique I. Lucini, Auteur Année de publication : 2011 Article en page(s) : pp. 289-293 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Lantana canescens Lantana tilcarensis Lantana trifolia Aloysia citriodora Aloysia gratissima Aloysia castellanosii Aloysia catamarcensis Verbenaceae essential oil composition Sarbinene 1,8-cineole α-thujone Carvone Geranial Thymol Geranyl acetate β-elemene (Z)-β-farnesene α-humulene Germacrene D (E)-β-farnesene γ-cadenene Spathulenol α-muurolol Index. décimale : 646 Résumé : The chemical composition of essential oil samples of the aerial parts of Lantana canescens, Lantana tilcarensis, Lantana trifolia, Aloysia citriodora, Aloysia gratissima, Aloysia castellanosii and Aloysia catamarcensis from northwest Argentina, phytogeographic areas of Yungas, Puna, Parque Chaqueño and Monte, have been analyzed by GC and GC/MS. The main oil component group present in the oils of the aerial parts of Lantana species were sesquiterpene hydrocarbons (> 24.8%). In contrast, the main compound group found in the oils of Aloysia species were oxygenated monoterpenes (> 19.6%). The comparison with previous studies performed by other authors points to a significant variation in the chemical composition of essential oil depending on the origin of the plants.

Two solvents were studied for extracting the oils, hexane and isopropanol.
The composition of N. sativa seeds varieties having four location origins in Algeria, were determined. Alcohols and ketones formed the main proportion using the two solvents, respectively (hexane: 27.4–36.1%, isopropanol: 40.2–59.0%) and (hexane: 39.9–44.3%, isopropanol: 17.5–50.7%), among which thymoquinone and thymohydroqui-none were the predominant antioxidant compounds.
The monoterpene hydrocarbons constitute relatively the lower fraction compared to the precedent chemical families, particularly by using the isopropanol solvent.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2010.9700335 [article] Chemical composition of volatile oils from algerian nigella sativa L. seeds [texte imprimé] / Farid Benkaci-Ali, Auteur ; Aoumeur Baaliouamer ; Jean Paul Wathelet, Auteur . - 2011 . - pp. 318-322.

Mots-clés : Nigella sativa Ranunculaceae p-Cymene Thymoquinone Thymohydroquinone GC GC/MS Index. décimale : 646 Résumé : The chemical composition of the volatiles obtained from the fixed oils of Nigella sativa L. seeds growing in Algeria was investigated by GC and GC/MS analysis. Two solvents were studied for extracting the oils, hexane and isopropanol.
The composition of N. sativa seeds varieties having four location origins in Algeria, were determined. Alcohols and ketones formed the main proportion using the two solvents, respectively (hexane: 27.4–36.1%, isopropanol: 40.2–59.0%) and (hexane: 39.9–44.3%, isopropanol: 17.5–50.7%), among which thymoquinone and thymohydroqui-none were the predominant antioxidant compounds.
The monoterpene hydrocarbons constitute relatively the lower fraction compared to the precedent chemical families, particularly by using the isopropanol solvent.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2010.9700335

Among the 74 components quantified in Setoka oil, 24 terpene hydrocarbons and 50 oxygenated compounds were identified, with peak weight percentages of 82.6 % and 16.8%, respectively. The major components of Setoka oil were limonene (77.3%), (Z)-nerolidol (4.2%), myrcene (1.9%), (E)-2-dodecenal (1.8%) and cis-carveol (1.0%). Although limonene was the most prominent component in Setoka oil, its content was relatively low compared to the commonly encountered citrus peel oils. A peculiarity of the volatile profile of Setoka oil was the ratio of alcohols (8.8%) to aldehydes (4.9%), which resulted from the relative abundance of (Z)-nerolidol and cis-carveol. The level of esters (1.7%) was another characteristic of Setoka oil.

In addition, β-pinene (15.1%), camphor (15.3%), carotol (7.3%), α-pinene (7.8%) and camphene (7.0%) were also present in leaf oil, whereas in the rhizome oil α-fenchyl acetate (13.1%), α-terpineol (9.6%), β-pinene (8.1%) and camphene (7.0%) were the other main constituents.

The oils were analyzed for their chemical composition by capillary GC and GC/MS. A total of 18 compounds were identified representing about 96.4% of leaf and 97.8% of rhizome oils, respectively. 1,8-cineole was the major component in both leaf (25.4%) and rhizome (34%) oils.

Traces of acetophenone, 9-epi-β-caryophyllene, (E)-4,8-dimethylnona-1,3,7-triene, (E,E)-farnesol, (E,E)-farnesyl acetate, hexahydrofarnesyl acetone, isovaleric acid, 2-methylbutyric acid, 5-methylfurfural, 1-octen-3-one, 2-pentylfuran, phenylacetaldehyde, phytol, toluene, and p-vinylguaiacol were identified, possibly for the first time, in Patchouli oil.

A comparison was made between the results obtained by HSME and a conventional hydrodistillation method. From 36 volatile components found in the hydrodistillated extract, 20 were identified and quantified in the HSME extract. The major components for both isolates were geraniol (34.9–37.2%), geranyl acetate (15.3–18.7%), geranial (9.0–11.2%), nerol (6.4–8.3%) and neral (7.1–9.3%).DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.tandfonline.com/doi/abs/10.1080/10412905.2010.9700347 [article] Headspace solvent microextraction of volatile components of thymus daenensis [texte imprimé] / Payman Hashemi, Auteur ; Mir Mehdi Abolghasemi, Auteur ; Hatam Hassanvand, Auteur . - 2011 . - pp. 365-368.
