Titre : Free and glycosidically bound volatiles in curry leaves (Murraya koenigii) (L) spreng. Type de document : texte imprimé Auteurs : K. P. Padmakumari, Auteur Année de publication : 2009 Article en page(s) : pp. 479-481 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Murraya koenigii Rutaceae Curry leaf Glycosides Essential oil composition Heptanal Linalool β-caryophyllene Résumé : Free and glycosidically bound aroma compounds from Murraya koenigii (L.) Spreng, were isolated and separated by Amberlite XAD-2 column. The fraction containing the free aroma compounds was eluted with pentane: diethyl ether (1:1). Aroma compounds from the bound fraction were released by β-glucosidase hydrolysis. Samples were analyzed by GC and GC/MS. Sixty-seven constituents were found to be present in the bound fraction where linalool was found to be the main constituent. In the free aroma fraction, seventy-eight constituents were present with octyl acetate being found as the main constituent. In the hydrodistilled oil, fifty-six compounds were identified and β-caryophyllene was the main compound.

Titre : Superheated water extraction of lavandula latifolia medik volatiles : Comparison with conventional techniques Type de document : texte imprimé Auteurs : Mohammad H. Eikani, Auteur ; Fereshteh Golmohammad, Auteur ; Soheila Shokrollahzadeh, Auteur Année de publication : 2009 Article en page(s) : pp. 482-487 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Lavandula latifolia Lamiaceae Spike lavender Essential oil composition Superheated water extract composition Extract composition 1,8-cineole Linalool Borneol Résumé : A comparative study of superheated water extraction (SWE) with two conventional volatile isolation methods including hydrodistillation and Soxhlet extraction was performed on spike lavender (Lavandula latifolia Medik.). The effect of operating conditions such as temperatures from 100–175°C, pressures from 20–40 bar and flow rates from 1–4 mL/min on the extraction process was investigated. The experiments were carried out using a laboratory-built apparatus. Separation and identification of the components were carried out by GC-FID and GC/MS. The SWE of L. latifolia shows the highest extraction efficiency at 150°C, 3 mL/min and 20 bar. At the optimum operating conditions, the extraction efficiency was as high as that for hydrodistillation and Soxhlet extraction methods. The SWE method was quicker and more selective for the valuable oxygenated constituents.

Monoterpenes hydrocarbons were also predominant in the oil of subsp. veronense, while sesquiterpenes and aliphatic hydrocarbons were found in the oil of subsp. perforatum. Such quantitative differentiation in the oil composition of the flowers may be useful as a chemotaxonomic intraspecific discriminatory character.

Titre : Essential oil composition of hypericum ‘Hidcote’ Type de document : texte imprimé Auteurs : Filippo Maggi, Auteur ; Bruno Tirillini, Auteur ; Sauro Vittori, Auteur Année de publication : 2009 Article en page(s) : pp. 539-541 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Hypericum ‘Hidcote’ Guttiferae Essential oil composition β-pinene Résumé : The essential oil of the artificial hybrid Hypericum ‘Hidcote’, one of the most cultivated St. John's worts in European and American gardens, was analyzed for the frist time by GC and GC/MS. Forty-six components were identified, representing 91.5% of the oil. The sesquiterpene fraction gave the highest contribution (68.4%), whilst monoterpenes amounted to 22.5%. The major constituents were β-pinene (11.9%), α-humulene (7.4%), β-caryophyllene (6.5%) and α-selinene (5.4%). Results confirm that hybridization may generate novel secondary chemistry in plants.

Buser was isolated by steam distillation from fresh aerial tissues and analyzed by GC-FID and GC/MS. Fresh samples were collected in two experimental sites located in Western alpine region (Alpe Gianna and Alpe Caugis, Val Pellice, Piedmont, Italy). The yield in essential oil was 0.16 ± 0.04% of fresh material. A wide range in volatile quantitative composition was detected. Terpenes and alcohols were identified as the major compounds representing the 36.9% and 30.6% of the total oil, and quantified as 47.3 μg/g fresh weight and 39.2 μg/g fresh weight, respectively. Aldehydes were quoted as 15.4% of the total oil (19.7 μg/g fresh weight), followed by acids 2.3% (3.0 μg/g fresh weight), esters 1.0% (1.3 μg/g fresh weight) and unidentified 0.5% (0.7 μg/g fresh weight). Dill apiole, coumarin, myristicin, vanillin, eugenol, apiole and p-vinyl guaiacol, altogether quoted as 4.5% of the total oil (5.8 μg/g fresh weight), were also detected.

Sample preparation consists of simple diluting of lavender oil 1+1 or 1+2 m/m with isopropanol or 1,4-dioxane. Pyrolytic graphite tubes, W-impregnated tubes and pyrolytic graphite tubes coated with Pt are proposed as atomizers for correct direct ETAAS measurement of studied elements. Calibration curves prepared with aqueous standards diluted in the respective organic solvent are recommended for the quantification of trace elements in lavender oil. The detection limits achieved are well below the maximum permissible concentrations for the studied elements in cosmetic or food products. Within-run and between-run precisions are between 2–7% and 3–10%, respectively at trace levels: Cd (0.5–5 ng/g); Bi, Cr, Cu, Ni, Sb, Pb (1–50 ng/g) and Fe, Mn (20–1000 ng/g).

The results were submitted to Principal Components and Clusters Analysis which enabled four groups of oils to be distinguished with regard to specimens and harvest seasons: clusters I and II with only E. grandis samples collected in the cold and dry winter and the hot and humid summer, which were characterized by a high percentage of isoleptospermone (9.6% and 13.2%), α-pinene (12.2% and 24.7%), p-cymene (20.5% and 14.5%), and α-terpineol (14.3% and 4.9%), respectively; clusters III and IV only associated with E. urophylla samples collected in summer and winter with 1,8-cineole (36.6% and 44.7%) and α-terpinyl acetate (7.0% and 11.7%) rich oils. Canonical discriminant analysis showed that it is possible to accurately predict 96% well-classification in the original clusters using α-pinene, 1,8-cineole, α-terpineol, and isoleptospermone as predictor variables.

Sixty-two (62) components were identified from the leaf oils which constituted ca. 99% of the oils, while sixty-three (63) components were identified from the bark oils which constituted ca. 97% of the oils. Monoterpenes represented the major components of the oils with α-pinene (49.8% and 34.8%), β-pinene (11.0% and 10.6%), terpinolene (0.7% and 13.4%) and α-terpineol (5.7% and 8.9%) being the major component. Of the sesquiterpenes, the predominant components were β-caryophyllene (4.8% and trace) and α-humulene (3.4% and 0.7%). The oil exhibited toxic action against adult sweet potato weevils, Cylas formicarius elegantulus (Summer), the most destructive pest of sweet potato (Ipomoea batatas). No antioxidant activity was observed for the oils when subjected to the DPPH assay.
