Public ISBD [article]  in The journal of essential oil research > Vol. 20 n°6 (Novembre/Décembre 2008) . - pp. 530-532 Titre : Essential oil composition of two lantana species from mountain forests of pernambuco (Northeast of Brazil) Type de document : texte imprimé Auteurs : José C. S. De Oliveira, Auteur ; Ilzenayde A. Neves, Auteur ; Claudio A. G. Da Camara, Auteur Année de publication : 2009 Article en page(s) : pp. 530-532 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Lantana  camara  Lantana  fucata  Verbenaceae  Essential  oil  composition  Germacrene  D  Caryophyllene  oxide  Germacrene  D-4-ol  Gossonorol  β-caryophyllene  Bicyclogermacrene  Bulnesol Résumé : The essential oils of Lantana camara L. and L. fucata Lindl. leaves collected in the region of Mata Serrana in the municipality of Brejo da Madre de Deus in Pernambuco—Brazil were obtained by hydrodistillation and analyzed by GC and GC/MS. Twenty-five compounds were identified in L. camara, representing 99.4% of the leaf oil constituents, while 15 compounds were identified in L. fucata, representing 97.1% of the leaf oil constituents. The major compounds present in the oil of L. fucata were caryophyllene oxide (27.9%), gossonorol (18.2%), β-caryophyllene (12.3%) and bulnesol (10.8%), whereas those in the oil of L. camara were germacrene D (28.6%), germacrene D-4-ol (19.9%), β-caryophyllene (16.2%) and bicyclogermacrene (14.7%).

Volatile constituents of the fruits of clusia nemorasa G.mey. from different region of atlantic coast restingas of pernambuco (Northeast of Brazil) / José C. S. De Oliveira in The journal of essential oil research, Vol. 20 n°3 (Mai/Juin 2008)

Da Camara, Auteur Année de publication : 2008 Article en page(s) : pp. 219-222 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Clusia  nemorosa  Clusiaceae  Essential  oil  composition  β-caryophyllene  γ-muurolene  Caryophyllene  oxide  α-humulene  δ-cadinene Résumé : The volatile components of the fruits from nine collections of Clusia nemorosa G. Mey. from two municipalities (Tamandaré: T1–3 and Cabo de Santo Agostinho: N1–3; G1–3) of the coastal region of Pernambuco, Northeast of Brazil, in two kind of soil, rocky rich in iron (N1–3) and sandy clays (T1–3 and G1–3), were analyzed by GC and GC/MS. The isolated oils were obtained in similar yields, 0.1–0.3 % (w/w) and 0.1–0.2% (w/w) in the samples from Taman- daré (T1–3) and Fortress Nazaré (N1–3) and in the samples from Gaibú (G1–3), respectively. The oil samples can be characterized by the abundance of sesquiterpene hydrocarbons, while the percentage of oxygenated sesquiterpenes was higher in the samples collected in Tamandaré (T1–3: 20.4—22.0%) and Gaibú (G1–3: 17.6–20.4%). Monoterpenes hydrocarbons were totally absent in all samples. All samples showed β-caryophyllene (37.3–48.6%) as the principal component. Based on the information of other major components, two subtypes of C. nemorosa growing wild in Pernambuco, Brazil, can be established.
