Abstract

Plants of the Lamiaceae family have been used for thousands of years in cooking, as well as phyto- and aromatherapy. Their essential oils are characterized by high antioxidant and other types of biological activities. In our study, the phytochemical profile and quantification of the essential oil components of thyme, marjoram, and sage were analyzed by gas chromatography with mass-spectrometric detection (GC-MSD). The antioxidant properties of the samples were evaluated using total antioxidant parameters (total antioxidant capacity (TAC), ferric reducing power (FRP), antioxidant activity (AOA) towards 2,2-diphenyl-1-picrylhydrazyl (DPPH•), and total phenolics by Folin–Ciocalteu method). The obtained FRP was 46–321-fold lower than TAC, which is consistent with the contents of phenolics identified in the samples. Terpenes, isopropylmethylphenols, and eugenol turned out to be the major components of all essential oils and determined their TAC and AOA. The Folin–Ciocalteu method was applicable to the thyme essential oil only. Its FRP, which is based on the reaction of phenolic antioxidants with electrogenerated ferricyanide ions, agreed well with the total phenolic contents (329 ± 17 and 334 ± 15 mg of carvacrol per mL, respectively). The thyme essential oil had the highest antioxidant parameters, while sage showed the weakest antioxidant properties. Positive correlations (r = 0.8846–0.9964) of the antioxidant parameters were obtained.
兰科植物商品精油抗氧化性能评价及GC-MSD分析
千百年来,兰科植物一直被用于烹饪,以及植物和芳香疗法。它们的精油具有高抗氧化性和其他类型的生物活性。采用气相色谱-质谱联用技术(GC-MSD)对百里香、马郁兰和鼠尾草的挥发油成分进行了定量分析。采用总抗氧化参数(总抗氧化能力(TAC)、铁还原力(FRP)、对2,2-二苯基-1-picrylhydrazyl (DPPH•)的抗氧化活性(AOA)和总酚类物质(Folin-Ciocalteu法)评价样品的抗氧化性能。所得FRP比TAC低46 - 321倍,这与样品中酚类物质的含量一致。萜烯、异丙基甲基苯酚和丁香酚是所有精油的主要成分,并测定了它们的TAC和AOA。Folin-Ciocalteu法仅适用于百里香精油。其基于酚类抗氧化剂与电生成的铁氰化物离子反应的FRP与总酚含量(分别为329±17和334±15 mg / mL)吻合良好。百里香精油的抗氧化性能最高,鼠尾草精油的抗氧化性能最弱。各抗氧化参数呈显著正相关(r = 0.8846 ~ 0.9964)。
