Eugenia florida DC. belongs to the Myrtaceae family, which is present in almost all of Brazil. This species is popularly known as pitanga-preta or guamirim and is used in folk medicine to treat gastrointestinal problems. In this study, two specimens of Eugenia florida (Efl) were collected in different areas of the same region. Specimen A (EflA) was collected in an area of secondary forest (capoeira), while specimen B (EflB) was collected in a floodplain area. The essential oils (EOs) were extracted from both specimens of Eugenia florida by means of hydrodistillation. Gas chromatography coupled to mass spectrometry (GC/MS) was used to identify the volatile compounds present, and the antioxidant capacity of the EOs was determined by antioxidant capacity (AC-DPPH) and the Trolox equivalent antioxidant (TEAC) assay. For E. florida, limonene (11.98%), spathulenol (10.94%) and α-pinene (5.21%) were identified as the main compounds of the EO extracted from sample A, while sample B comprised selina-3,11-dien-6α-ol (12.03%), eremoligenol (11.0%) and γ-elemene (10.70%). This difference in chemical composition impacted the antioxidant activity of the EOs between the studied samples, especially in sample B of E. florida. This study is the first to report on the antioxidant activity of Eugenia florida DC. essential oils.

Schinus fasciculata and S. praecox (Anacardiaceae) can be found among the characteristic vegetation components of the phytogeographic province of the Espinal. The essential oils from these two species have been obtained from fresh material by hydrodistillation and analyzed by GC and GC-MS. We have compared the chemical composition of the oils obtained from samples collected at two different natural environments and at different phenological phases. The antioxidant activity of these oils was evaluated by the DPPH assay. S. fasciculata and S. praecox showed significant differences in their chemical composition as well as in their radical scavenger ability. The essential oil from samples of S. fasciculata attacked by plant-lice (Hemiptera, Psylloidea) was the more active one, with inhibition percentages higher than that of the reference compound.
