Abstract Origanum vulgare L. var. aureum is an aromatic medicinal plant belonging to the Lamiaceae family, rich in essential oils and antioxidants. Its specific chemical composition represents an important source of biologically active principles with diverse applications in food products and nutraceuticals. The aim of this study was to determine the differences between chemical composition of volatile oils, phenolic content and antioxidant activity of different plants parts: leaves, flowers, and stems. Essential oils from leaves and flowers had similar compositions with only few differences between γ-terpinene and trans-ß-ocimene. Total phenolic content and antioxidant activity were determined for the hydro-alcoholic extract obtained from post-distillation oregano waste material. The total phenolic content was determined using Folin-Ciocalteu reagent and varied from 3173 to 6522 mg GAE/L. The major compounds identified by HPLC were syringic acid, pyrocatechol, and catechin. Furthermore, all extracts showed high antioxidant activity, ranging from 31.3 to 44.5 mg GAE/L, with an inhibition percent varying from 63.1 to 88.6%.

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.
