The antioxidant potential of the essential oils (EO) of 24 basil genotypes was assessed by 4 distinct in vitro evaluation methods. Different combinations of the major compounds found in the EO were also tested to identify those combinations responsible for the antioxidant activity of the volatile oils and verify the occurrence of synergism or antagonism between them. Results indicate that 9 EO exhibited promising antioxidant potential, with at least 52.68% of inhibition of the linoleic acid peroxidation at 10 µL/mL and 76.34% of inhibition of the DPPH radical at 1 µL/mL. The major compound eugenol had the highest antioxidant activity. The antioxidant activity of these EO cannot be explained solely by the presence of the major compounds. Despite the influence of eugenol, the antioxidant activity is also related to the synergism between other minor compounds found in the EO. This fact confers a potent antioxidant activity to some basil EO.
采用 4 种不同的体外评价方法评估了 24 种罗勒基因型精油（EO）的抗氧化潜力。还测试了精油中主要化合物的不同组合，以确定那些对挥发性油的抗氧化活性负责的组合，并验证它们之间是否存在协同作用或拮抗作用。结果表明，9 种 EO 表现出有希望的抗氧化潜力，在 10µL/mL 时至少有 52.68%抑制亚油酸过氧化，在 1µL/mL 时抑制 DPPH 自由基 76.34%。主要化合物丁香酚具有最高的抗氧化活性。这些 EO 的抗氧化活性不能仅仅通过主要化合物的存在来解释。尽管存在丁香酚的影响，但抗氧化活性也与精油中其他少量化合物之间的协同作用有关。这一事实赋予了一些罗勒 EO 强大的抗氧化活性。
