Chemical composition and antioxidant activity of the essential oil of Chev. (Lauraceae) were investigated for the first time from Viet Nam. Leaf essential oil was hydrodistilled and analysed by GC and GC-MS that totally identified 32 terpenoid compounds (accouting for 89.18% of the total oil) with β-patchoulene (25.74%) and β-caryophyllene (12.81%) as two major sesquiterpene hydrocarbons compounds. The antioxidant potential of leaf essential oil was evaluated using DPPH, ABTS and FRAP assays, and revealed a moderate-to-high activity comparable with already known antioxidant standard Trolox.
首次对越南产 Chev.（樟科）叶精油的化学成分和抗氧化活性进行了研究。通过水蒸气蒸馏法提取精油，并采用 GC 和 GC-MS 进行分析，共鉴定出 32 种萜类化合物（占总油量的 89.18%），其中 β-石竹烯（25.74%）和 β-丁香烯（12.81%）为两种主要的倍半萜类碳氢化合物。采用 DPPH、ABTS 和 FRAP 测定法评价了叶精油的抗氧化潜力，结果表明其具有中等至高的活性，可与已有的抗氧化标准 Trolox 相媲美。
