dc.description.abstractÓleos essenciais (EOs) foram extraídos de Eugenia patrisii, E. punicifolia e Myrcia tomentosa, espécimes A e B, usando hidrodestilação. Cromatografia gasosa acoplada à espectrometria de massas (GC/MS) foi usada para identificar os constituintes voláteis presentes, e a capacidade antioxidante dos OEs foi determinada usando ensaios de difenilpicril-hidrazil (DPPH) e capacidade antioxidante equivalente a trolox (TEAC). Para E. patrisii, germacreno D (20,03%), biciclogermacreno (11,82%) e (E)-cariofileno (11,04%) foram identificados como os principais constituintes dos OEs extraídos do espécime A, enquanto o espécime B compreendia principalmente γ-elemeno (25,89%), germacreno B (8,11%) e (E)-cariofileno (10,76%). Os OEs do espécime A de E. punicifolia continham β-Elemeno (25,12%), (E)-cariofileno (13,11%) e biciclogermacreno (9,88%), enquanto o espécime B era composto de (E)-cariofileno (11,47%), biciclogermacreno (5,86%), β-pineno (5,86%) e γ-muuroleno (5,55%). O espécime A de M. tomentosa foi caracterizado por γ-elemeno (12,52%), germacreno D (11,45%) e (E)-cariofileno (10,22%), enquanto o espécime B continha espatulenol (40,70%), α-zingibereno (9,58%) e γ-elemeno (6,89%). Além disso, a composição química dos OEs foi qualitativa e quantitativamente afetada pelo período de coleta. Além disso, os OE dos espécimes estudados, especialmente o espécime A de E. punicifolia, apresentaram maior atividade antioxidante em DPPH do que em TEAC, representada por uma porcentagem de inibição significativamente alta (408,0%).pt_BR

dc.description.resumoEssential oils (EOs) were extracted from Eugenia patrisii, E. punicifolia, and Myrcia tomentosa, specimens A and B, using hydrodistillation. Gas chromatography coupled with mass spectrometry (GC/MS) was used to identify the volatile constituents present, and the antioxidant capacity of EOs was determined using diphenylpicryl-hydrazyl (DPPH) and trolox equivalent antioxidant capacity (TEAC) assays. For E. patrisii, germacrene D (20.03%), bicyclogermacrene (11.82%), and (E)-caryophyllene (11.04%) were identified as the major constituents of the EOs extracted from specimen A, whereas specimen B primarily comprised γ-elemene (25.89%), germacrene B (8.11%), and (E)-caryophyllene (10.76%). The EOs of E. punicifolia specimen A contained β-Elemene (25.12%), (E)-caryophyllene (13.11%), and bicyclogermacrene (9.88%), while specimen B was composed of (E)-caryophyllene (11.47%), bicyclogermacrene (5.86%), β-pinene (5.86%), and γ-muurolene (5.55%). The specimen A of M. tomentosa was characterized by γ-elemene (12.52%), germacrene D (11.45%), and (E)-caryophyllene (10.22%), while specimen B contained spathulenol (40.70%), α-zingiberene (9.58%), and γ-elemene (6.89%). Additionally, the chemical composition of the EOs was qualitatively and quantitatively affected by the collection period. Furthermore, the EOs of the studied specimens, especially specimen A of E. punicifolia, showed a greater antioxidant activity in DPPH rather than TEAC, as represented by a significantly high inhibition percentage (408.0%).pt_BR
