Abstract

Natural extracts present antioxidant activity and can replace synthetic antioxidants. This study aimed to extract essential oil from Pitanga (Eugenia uniflora L.) leaves and evaluate its chemical composition, as well as antioxidant and antibacterial activities. The essential oil was obtained by hydrodistillation for 3 hours with a yield of 1.34 ± 0.18 %. The total antioxidant activity was evaluated by the DPPH and phosphomolybdenum methods. The oil presented an IC50 value of 100.96 µL mL‑1 and 1503.44 ± 29.48 mg α‑tocopherol mL-1 of oil. The major compounds identified by the GC-MS were germacrone (13.57%), spathulenol (7.49%), curzerene (5.31%) and α-cadinol (4.70%). The oil was also evaluated for its antimicrobial activity and was effective against Staphylococcus aureus. These results show that essential oil of pitanga leaves have good antioxidant and antimicrobial activity, being an alternative source of bioactive compounds.

牡丹挥发油的生物活性研究叶子

天然提取物具有抗氧化活性，可替代合成抗氧化剂。本研究旨在从独角藤(Eugenia uniflora L.)叶中提取精油，并对其化学成分、抗氧化和抗菌活性进行评价。加氢蒸馏3 h，得率为1.34±0.18%。采用DPPH法和磷钼法测定其总抗氧化活性。精油的IC50值为100.96µL mL-1， α -生育酚mL-1为1503.44±29.48 mg。GC-MS鉴定的主要化合物为德国酮(13.57%)、spathulenol(7.49%)、curzerene(5.31%)和α-cadinol(4.70%)。该油还被评估其抗菌活性，并对金黄色葡萄球菌有效。这些结果表明，皮丹加叶精油具有良好的抗氧化和抗菌活性，是生物活性物质的替代来源。
