Public ISBD [article]  in The journal of essential oil research > Vol. 21 N° 4 (Juillet/Août 2009) . - pp. 337-341 Titre : Chemical studies of leaf essential oils of three species of juniperus from tensift al Haouz-Marrakech region (Morocco) Type de document : texte imprimé Auteurs : Nadia Achak, Auteur ; Abderrahmane Romane, Auteur ; Mohamed Alifriqui, Auteur Article en page(s) : pp. 337-341 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Juniperus  thurifera  var.  africana  Juniperus  phoenicea  Juniperus  oxycedrus  Cupressaceae  Essential  oil  composition  Sabinene  γ-terpinene  13-epi-manoyl  oxide  (Z)-6-pentadecen-2-one  α-pinene Index. décimale : 646 Résumé : Volatile components from fresh and air-dried leaves of Juniperus thurifera var. africana, J. phoenicea and J. oxycedrus (Cupressaceae) were isolated by direct water distillation (Clevenger-type apparatus) and analyzed using GC (FID) and GC/MS. The essential oils from leaves of J. thurifera var. africana were characterized by a high sabinene content (16.5–21.8%), γ-terpinene (9.3–11.5%), and α-pinene (7.6–9.1%). The major components for J. phoenicea were α-pinene (38.2–58%) and δ-3-carene (7.6%), while 13-epi-manoyl oxide (12.5–13.2%), (Z)-6-pentadecen-2-one (11.5–12.2%), and α-pinene (8.5–17.1%) were the major components found in the leaf oils of J. oxycedrus. The fresh leaves of J. thurifera var. africana contained 1.46% oil, while the yield was 1.14% from the dried leaves. The oil yields from the dried leaves of J. phoenicea and J. oxycedrus were 0.94% and 0.01%, respectively. Air-drying moderately effected the qualitative and quantitative composition of the oils.

Effect of the leaf drying and geographic sources on the essential oil composition of juniperus thurifera L. var. africana maire from the tensift—al haouz, marrakech region / Nadia Achak in The journal of essential oil research, Vol. 20 n°3 (Mai/Juin 2008)

The oil yields from fresh leaves showed on differences among geographical sources. Air dried leaves appeared to yield more oil at the highest elevation (1.03%, Ait Lkak, 2900 m) than lower sites (0.67%, Plateau of Matat, 2200 m; 0.57%, Forêt Islane, 2000 m). The essential oils from each geographic site had very similar composition in fresh versus air dried leaves. The essential oils from provenance Ait Lkak and Plateau of Matat were very similar and characterized by a high sabinene content (21.2, 35.9%), in contrast to 10.% sabinene from the provenance Forêt Islane. The oil from Foret Islane had a high δ-cadinene content with 12.7%, whereas Aik Akak and Plateau of Matat contained only 0.6 and 0.8%. The Moroccan oils (J. thurifera var. africana) were compared to European J. thurifera var. thurifera (Spain) oil. Moroccan oils were found to be higher sabinene and limonene than the European oil.
