Lage, Auteur Article en page(s) : pp. 52-54 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Alpinia  zerumbet  Alpinia  purpurata  Zingiberaceae  Essential  oil  composition  1,8-cineole  γ-terpinene  p-mentha-1,3,8-triene  α-pinene  β-pinene  Terpinen-4-ol  Terpinen-7-al  Caryophyllene  oxide Index. décimale : 646 Résumé : Fresh leaves of Alpinia zerumbet and A. purpurata (Zingiberaceae) were collected in Rio de Janeiro city and subjected to hydrodistillation; their chemical composition was analyzed by GC/MS. These species are used as ornamental plants and in folk medicine. Variations in the leaf oils content and composition of A. zerumbet were found between April and August 2005. In April, the main constituents identified in leaf oil of A. zerumbet were terpinen-7-al (40.5%) and sabinene hydrate (15.4%); in August, the major components identified were terpinen-4-ol (29.4%) and 1,8-cineole (23.1%). Leaf oil of A. purpurata was rich in β-pinene (34.7%) and α-pinene (11.8%).

Leaf secretory structure and volatile compounds of eugenia copacabanensis kiaersk. (Myrtaceae) / Rosani do Carmo de O. Arruda in The journal of essential oil research, Vol. 23 N° 5 (Septembre/Octobre 2011) 

Public ISBD [article]  in The journal of essential oil research > Vol. 23 N° 5 (Septembre/Octobre 2011) . - pp. 1-6 Titre : Leaf secretory structure and volatile compounds of eugenia copacabanensis kiaersk. (Myrtaceae) Type de document : texte imprimé Auteurs : Rosani do Carmo de O. Arruda, Auteur ; Cristiane P. Victório, Auteur Année de publication : 2012 Article en page(s) : pp. 1-6 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Eugenia  copacabanensis  Kiaersk  Myrtaceae  Atlantic  rainforest  α-pinene  β-pinene  Caryophyllene  Restinga  Secretory  activity  Simultaneous-distillation  extraction  Volatile  composition Index. décimale : 646 Résumé : Eugenia copacabanensis Kiaersk. (Myrtaceae) is restricted to salt marshes or restinga areas along the southeastern coast of Brazil. This work analyzes the leaf secretory structures and volatile compounds produced in E. copacabanensis plants collected in the Marambaia Restinga of Rio de Janeiro City. Simultaneous-distillation extraction (SDE), when combined with GC-FID and GC/MS analyses, revealed α-pinene (20.2%) and β-pinene (50.4%) as the major volatiles of this plant, proving that it is rich in monoterpenes. trans-Caryophyllene (10.3%) was the only sesquiterpene identified. Using light microscopy, E. copacabanensis leaves presented numerous randomly distributed oil secretory cavities in the mesophyll, while histochemical tests showed the presence of terpenoids and lipophilic substances accumulated in secretory cavities and parenchyma cells.
