Abstract

The chemical composition of the essential oil obtained from the branches of Ocotea paranaensis was studied by gas chromatography/mass spectrometry (GC/MS). Twenty-seven compounds, comprising 94.82% of the total components, were identified. The oil showed relatively high concentration of sesquiterpenes (62.96%), oxygenated sesquiterpenes (33.33%), and diterpene (3.70%). Regarding the major compounds, Z-nerolidol (19.16%), germacrene D (12.92%) and -bulnesene (8.47%) could be highlighted, which corresponded to 40.55% of the substances that were found. The essential oil from Ocotea paranaensis has phosphomolybdenum reducing action and is moderately toxic to the Artemia salina (LC50 = 147.91 g/mL). It showed haemolytic potential and moderate activity against Staphylococcus aureus, (minimum inhibitory concentration MIC = 250 g/mL) and Pseudomonas aeruginosa (MIC = 500 g/mL). No satisfactory cytotoxicity results were observed in lineage H460 and HeLa.
