Schinus molle L. is a medicinal and aromatic plant used in traditional medicine for his therapeutic properties. The leaves and
berries of Schinus molle L. were collected in Iheddaden and Amriw (Bejaia, Algeria) and the essential oils were isolated by
hydrodistillation with yields between 0.26 and 0.80%. The chemotype of the essential oils was sesquiterpene group, cadinene
and cadinols subgroups. The cadinene subgroup was obtained from Iheddaden leaves and Amriw samples (leaves and berries)
with proportions between 16.1 and 23.4%, while the cadinols subgroup was only shown with Iheddaden berries (30.5%). The
antioxidant activities of the essential oils from leaves and berries of Schinus molle L. were low: IC50
DPPH were between
6.9 and 8.6 mg/mL, when IC50
ABTS varied between 0.7 and 5.0 mg/mL. Principal component analysis indicates that high
proportions of oxygenated sesquiterpenes promote the antioxidant activity of essential oils from Schinus molle L. against
ABTS radical, while the antioxidant activity against the DPPH radical requires the combination of the different chemical
families contained in the essential oils of Schinus molle L.
