Abstract: The essential oils from leaves, flowers, and fruits of Kielmeyera rugosa (family Clusiaceae) growing in Sergipe, north-eastern Brazil, were obtained by hydrodistillation using a Clevenger-type apparatus and analysed by GC-MS. Thirty-six components were identified in the oil from fruits, which was dominated by sesquiterpene hydrocarbons. The nine major components identified (representing 76-77% of the oil) were delta-valerolactone (1-9%), alpha-cubebene (3-4%), alpha-copaene (10-11%), beta-caryophyllene (11-16%), alpha-humulene (3-5%), alpha-selinene (4-5%), (EE)-alpha-farnesene (2-9%), delta-cadinene (23-32%) and 1-epi-cubenol (1-4%). In the leaf oil, 41 compounds were identified, with sesquiterpene hydrocarbons predominating. The 10 major constituents identified (representing 65-71% of the oil) were (Z)-3-hexen-1-ol (3%), alpha-cubebene (11-13%), alpha-copaene (11%), beta-cubebene (5-9%), beta-caryophyllene (9-13%), germacrene D (2-4%), cis-beta-guaiene (3%), alpha-selinene (6%), delta-cadinene (7-10%) and 1-epi-cubenol (3-4%). Of the 25 compounds found in the K. rugosa, flower oil, the three main components identified (representing 92.7% of the oil) were the benzenoid compounds, benzyl alcohol (18.6%), 2-phenylethanol (58.2%) and eugenol (15.9%).
