Abstract
The essential oil isolated from the resin of Aucoumea klaineana Pierre (Burseraceae) by Hydrodistillation was analyzed by capillary gas chromatography (GC) and combined Gas Chromatography/Mass Spectrometry (GC/MS). The analysis led to the identification of 28 components. This oil contained mainly monoterpenoids (96.06%) in which p-acetyl anisole is the single benzenic compound (0.18%). The predominant constituents in the essential oil were -3-carene (72.31%), p-cymene (3.76%), limonene (4.04%), terpinolene (6.28%) and -terpineol (4.34%). The essential oil showed antioxidant and weak DPPH radical scavenging activities and it displayed the inhibition of lipid peroxidation.
Key words: Aucoumea klaineana, Burseraceae, essential oil, antioxidant activity.
