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%).
