Popis: 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 δ-valerolactone (1–9%), α-cubebene (3–4%), α-copaene (10–11%), β-caryophyllene (11–16%), α-humulene (3–5%), α-selinene (4–5%), (E,E)-α-farnesene (2–9%), δ-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%), α-cubebene (11–13%), α-copaene (11%), β-cubebene (5–9%), β-caryophyllene (9–13%), germacrene D (2–4%), cis-β-guaiene (3%), α-selinene (6%), δ-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%).
