Weslati, Auteur Année de publication : 2013 Article en page(s) : pp. 475-480 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Rosa  canina  Rosa  sempervirens  Rosaceae  Essential  oils  Chemical  variability  Cluster  analysis Résumé : The chemical variability of the essential oils of Rosa canina L. and R. sempervirens L. flowers collected at seven localities from northern Tunisia was investigated by gas chromatography (GC) and GC–mass spectrometry (GC–MS). The essential oils yields ranged between 0.7% and 1.4% (v/f.w.) for R. canina and R. sempervirens, respectively. Forty-one components were identified in R. canina and twenty-six in R. sempervirens oils. Rosa canina essential oil, from plants collected at Ain Draham, was dominated by β-caryophyllene (32%) and geraniol (21%), whereas in the oils from plants collected at Boussalem n-heneicosane (29%), p-cymene (12%) and β-caryophyllene (11%) predominated. However, the oil isolated from the samples collected at Fernana was dominated by 2,4,6-trimethyl-octane (9%), n-undecane (8%) and geraniol (8%). p-Cymene (14%), limonene (11%) and γ-terpinene (11%) were the main components of the oil isolated from Feija samples. Rosa sempervirens oils, from plants collected at Ain Draham and Fernana, were characterized by a high 2-phenylethyl alcohol content (29% and 93%, respectively). The major components of the oil isolated from Tabarka samples were p-cymene (16%) and γ-terpinene (12%). Cluster analysis of the essential oils composition from the studied populations, confirmed the major chemical variability.
