The antioxidant activity of the essential oils, as well as of the organic and hydroethanolic extracts, of the fresh needles of 54 pine taxa was evaluated using the peroxy-oxalate and luminol chemiluminescence assays. Among all evaluated essential oils, and displayed the highest levels of activity. var. , followed by var. , exhibited the highest antioxidant capacity among the organic extracts, while the most active hydroethanolic extract was that of subsp. . Based on the overall levels of activity, the latter taxon was selected for phytochemical analysis targeting the isolation of the bioactive constituents. As such, the organic extract of subsp. was subjected to chromatographic separations to yield 11 secondary metabolites () that were evaluated for their antioxidant activity. Nonetheless, the isolated compounds were found to be less active than the crude extract, thus suggesting the potential role of synergism.
采用过氧草酸盐和鲁米诺化学发光分析法，对54种松树类群新鲜针叶中的挥发油以及有机提取物和氢乙醇提取物的抗氧化活性进行了评估。在所有评估的挥发油中，[具体两种挥发油未给出名称]表现出最高水平的活性。在有机提取物中，[具体松树品种未给出名称]变种，其次是[具体松树品种未给出名称]变种，表现出最高的抗氧化能力，而活性最高的氢乙醇提取物是[具体松树亚种未给出名称]亚种的提取物。基于总体活性水平，选择后一个分类群进行植物化学分析，以分离生物活性成分。因此，对[具体松树亚种未给出名称]亚种的有机提取物进行色谱分离，得到11种次生代谢产物（[具体次生代谢产物未给出名称]），并对其抗氧化活性进行了评估。然而，发现分离出的化合物活性低于粗提物，这表明协同作用的潜在作用。
