Titre : Comparison of essential oil of xanthogalum purpurascens lallem. obtained via different isolation techniques Type de document : texte imprimé Auteurs : G. Özek, Auteur ; T. Özek, Auteur ; K. H. C. Başer, Auteur Année de publication : 2006 Article en page(s) : pp. 181-184 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Xanthogalum purpurascens Umbelliferae Essential oil composition α -phellandrene β -phellandrene Résumé : The essential oil of Xanthogalum purpurascens Lallem. was obtained by hydrodistillation (HD), microdistillation (MD) and micro-steam distilled solid-phase micro extraction (MSD-SPME) techniques. The oils were then analyzed by GC and GC/MS. The composition of oils depended on the extraction method employed. The main components of the hydrodistilled oil were found to be α-phellandrene (32%), β-phellandrene (23%), isopropyl hexanoate (6%), limonene (5.3%), p-cymene (3.7%), α-pinene (3.2%) and bicyclogermacrene (3%).

Duran, M. Sagiroglu et H. Duman were obtained by hydrodistillation (HD), microdistillation (MD), micro-steam distilled solid-phase microextraction (MSD-SPME) techniques and then analyzed by GC and GC/MS methods. The oils showed similar composition with some quantitative differences. The main components of the oils were found to be α-humulene, germacrene D, naphthalene, terpinolene, p-cymene, γ-elemene and bornyl acetate.

Titre : Comparison of the essential oils of three endemic turkish heracleum species obtained by different isolation techniques Type de document : texte imprimé Auteurs : T. Özek, Auteur ; G. Özek, Auteur ; K. H. C. Başer, Auteur Année de publication : 2006 Article en page(s) : pp. 605-610 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Heracleum crenatifolium platytaenium sphondylium subsp Ternatum Umbelliferae Essential oil composition Octyl acetate butyrate Apiole Isolation techniques Résumé : The essential oils of three Turkish endemic Heracleum species, H. crenatifolium Boiss., H. platytaenium Boiss. and H. sphondylium L. subsp. ternatum (Velen.) Brummitt were obtained using hydrodistillation (HD), microwave-assisted hydro-distillation (MWHD), microdistillation (MD), micro steam distillation-solid-phase microextraction (MSD-SPME) techniques and analyzed by GC and GC/MS. Compositions of the oils isolated by different methods showed some differences. The main components in all the oils were found to be octyl acetate (19–95%) and octanol (0.6–5.0%). Octyl isovalerate (0.8–6.4%) and decyl acetate (0.5–4.3%) were the next most abundant constituents in the oil of H. crenatifolium. Octyl hexanoate (3.0–4.7%), (Z)-4-octenyl acetate (1.6–2.1%), octanol (0.7–1.0%) and decanal (0.7–1.2%) were the next major constituents in the oil of H. platytaenium. Octyl butyrate (34.6–41.0%), apiole (4.7–20.4%), (Z)-4-octenyl acetate (2.2–4.4%) and (Z)-4-octenyl butyrate (2.6–3.0%) were found as other main constituents in the oil of H. sphondylium subsp. ternatum.

(Cruciferae) was obtained by microdistillation and analyzed by both GC and GC/MS. Octyl acetate (21.2%) was identifed as the main constituent in the oil. Sulfur compounds responsible for the foul odor of the oil comprised 34.7%. They consisted of isopropyl isothiocyanate (16.9%), dimethyl trisulfde (8.8%), dimethyl disulfde (4.7%) and isobutyl isothiocyanate (4.3%).
