The essential oils (EOs) from the leaves of Schinus areira and one of its components, globulol, were studied for their antioxidant, antimutagenic and antipromutagenic activities. The chemical composition of the EOs obtained using hydrodistillation was determined using gas chromatography-mass spectrometry (GC-MS), and fractionated using reversed phase high performance liquid chromatography (RP-HPLC). The active compound (16.61%) isolated was identified by comparison of its 1H and 13C NMR spectroscopy with those reported in the literature. The antioxidant activity of the EOs and globulol were determined using two methods: crocin bleaching inhibition (Trolox Equivalent Value, TEV Krel = 1.16 ± 0.11 vs. 1.24 ± 0.22) and scavenging of the DPPH radical (IC50 = 38.75 ± 2.5 μg/mL vs. 5.60 ± 0.9 μg/mL). The antimutagenic and antipromutagenic activities were evaluated in vitro and ex vivo, using the Ames assay with five strains of Salmonella typhimurium with and without exogenous metabolic activation (rat liver fraction S9), against different mutagens. The result determined that globulol and EOs of S. areira at the applied doses do not exhibit any mutagenic effect and showed the highest antioxidant activity. Full article
