Chemical composition of the essential oil of juniperus phoenicea L. from Algeria / Tahar Dob in The journal of essential oil research, Vol. 20 N°1 (Janvier/Fevrier 2008) 

Public ISBD [article]  in The journal of essential oil research > Vol. 20 N°1 (Janvier/Fevrier 2008) . - pp. 15-20 Titre : Chemical composition of the essential oil of juniperus phoenicea L. from Algeria Type de document : texte imprimé Auteurs : Tahar Dob, Auteur ; Dahmane Dahmane, Auteur ; Chaabane Chelghoum, Auteur Année de publication : 2008 Article en page(s) : pp. 15-20 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Juniperus  phoenicea  Cupressacae  Essential  oil  composition  α-pinene  α-phellandrene Résumé : The chemical composition of the essential oil of Juniperus phoenicea from Algeria was investigated for the first time. The volatile oil was isolated by hydrodistillation in yield 0.80% and was analyzed by GC/FID and GC/MS techniques. One hundred and three constituents, representing 96.0% of the oil was identified, twenty-three being reported for the first time in J. phoenicea oil. The oil was characterized by the presence of high amounts of monoterpene hydrocarbons (62.2%) and by a lower percentage of oxygenated sesquiterpenes (8.8%), of which α-pinene (40.2%), α-phellandrene (14.7%) and elemol (3.9%) were the main compounds. Also the oil was characterized by the presence of three diterpenes constituents; manoyl oxide, abietadiene and cis-totarol amounting to 0.3%. A comparison with the composition of the oils of J. phoenicea (subspecies and varieties) of other countries reported in literature is discussed briefly.

Chemical composition of the essential oils of pistacia lentiscus L. from Algeria / Tahar Dob in The journal of essential oil research, Vol. 18 N° 3 (Mai-Juin 2006) 

Public ISBD [article]  in The journal of essential oil research > Vol. 18 N° 3 (Mai-Juin 2006) . - pp. 335-338 Titre : Chemical composition of the essential oils of pistacia lentiscus L. from Algeria Type de document : texte imprimé Auteurs : Tahar Dob, Auteur ; Dahmane Dahmane, Auteur ; Chaabane Chelghoum, Auteur Année de publication : 2006 Article en page(s) : pp. 335-338 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Pistacia  lentiscus  Anacardiaceae  Essential  oil  composition  α-pinene  Longifolene  Trans-β-terpineol  Sabinene Résumé : The essential oils of Pistacia lentiscus L. from three regions of Algeria (Algiers, Tizi-Ouzou and Oran) were isolated from aerial parts by hydrodistillation and were investigated by GC and GC/MS. Longifolene was predominant in the oils from Algiers (12.8%) and Tizi-Ouzou (16.4%), while α-pinene (19.0%) was the major constituent of the Oran oil. The other compounds of oils were present in important amounts; Algiers oil: γ-cadinene (6.2%)s, trans-β-terpineol (5.0%) and α-acorneol (4.6%); Tizi-Ouzou oil: trans-β-terpineol (15.6%), terpinen-4-ol (7.0%) and γ-muurolene (5.7%); Oran oil: trans-β-terpineol (13.1%), sabinene (12.6%) and β-pinene (6.5%). A comparison with oils from P. lentiscus of other countries reported in literature shows both qualitative and quantitative differences.
