Apel, Auteur Année de publication : 2009 Article en page(s) : pp. 504-506 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Drimys brasiliensis Winteracecae Essential oil composition Myrcene Limonene Spathulenol Cyclocolorenone Résumé : The chemical composition of essential oils obtained from fresh leaves and stem bark of Southeastern Brazilian native Drimys brasiliensis Miers were analyzed by GC and GC/MS and 37 compounds were identified. The oils from fresh leaves showed the presence of monoterpenes (53.9%) and sesquiterpenes (38.4%), with sabinene (9.5%), myrcene (10.5%), limonene (10.6%) and cyclocolorenone (16.0%) being the most abundant. The stem bark oil was characterized by predominance of sesquiterpenoids (87.6%) and the absence of monoterpenes, the main components being cyclocolorenone (28.3%) and spathuleneol (22.9%). A small amount of phenylpropanes (6.8–6.9%) was also detected in both oil samples.
