Ghosn, Auteur ; Cyril B. Chemali, Auteur ; Farah I. Zaknoun, Auteur Année de publication : 2006 Article en page(s) : pp. 443-444 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Dittrichia graveolens Inula Asteraceae Essential oil composition Borneol Bornyl acetate T-cadinol Résumé : Essential oils isolated from the aerial parts of two different Lebanese wild populations of Dittrichia graveolens were analyzed by GC and GC/MS. It was shown that around 90% of the total composition consisted of oxygenated compounds. The four major components identified were bornyl acetate (70.6–72.3%), T-cadinol (1.4–13.4%), borneol (2.7–12.4%), and caryophyllene oxide (1.9–2.3%), in addition to 21 minor ones. Oils from the two populations possessed a high content of bornyl acetate but differed with respect to borneol and T-cadinol. In comparison with oils of D. graveolens from other populations, it was found that the oil of D. graveolens of Lebanese origin was distinctly richer in oxygenated compounds.
