Abstract

The essential oil obtained by steam distillation from fresh leaves of Ocotea notata (Ness) Mez (Lauraceae) was analyzed by GC-MS and twelve compounds were identified, accounting for 83.3 % of the total components present in the essential oil. The sesquiterpenes Germacrene A (22.7 %) and β-Caryophyllene (22.9 %), and the monoterpenes α-Pinene, β-Pinene and Terpinolene (8.7 %, 6.9 % and 5,5 %respectively) were the main constituents. The oil was evaluated by means of the brine shrimp lethality test and showed high toxicity with an LC50 value of 2.37 μg/mL.
