Essential oil composition, phenolic, flavonoid and antioxidant activity of Kelussia odoratissima populations evaluated from the samples obtained from different regions in Isfahan (Keloose and Fereydunshahr) and Kohgiluye (Dishmook) provinces of Iran. The relationships between the compounds and climatic factors were also evaluated. Essential oil yield ranged from 1.16% in Keloose to 1.19% in Dishmook. The major compounds were (Z)-ligustilide (51.34–58.74%), thymol (4.46–8.76%), carvacrol (2.85–7.84%) and butylidenephthalide (2.84–4.86%). Total phenolic content of seed extracts varied from 22.23 (Keloose) to 40.88 (Dishmook) mg tannic acid equivalents (TAE) g ⁻¹DW. The similar trend was also obtained for total flavonoid content. Antioxidant activity of seed extracts was assessed using three food model systems including DPPH, beta-carotene bleaching and reducing power. In all model systems, seed extracts of Fereydunshahr revealed higher radical scavenging activity as compared with other populations and BHT (Butylated Hydroxy Toluene). In overall, Kelussia population collected from Kohgilooyeh province (Dishmook) possessed higher phenolic content, oil yield and (Z)-ligustilide, while the populations collected from Isfahan province (Fereydunshahr and Keloose) showed the highest extraction yield and antioxidant activity. Finally, clay soils were more appropriate for increasing of monoterpenes such as carvacrol and 1, 8-cineole, while phthalides such as (Z)-ligustilide were more affected by genetics background rather than environmental factors.

从伊朗伊斯法罕（Keloose和Fereydunshahr）和科吉卢耶（Dishmook）省的不同地区获得的样品中评估了香气假单胞菌种群的精油成分，酚类，类黄酮和抗氧化活性。还评估了化合物与气候因素之间的关系。精油收率从Keloose的1.16％到Dishmook的1.19％不等。主要化合物为（Z）-木脂苷（51.34–58.74％），百里酚（4.46–8.76％），香芹酚（2.85-7.84％）和丁烯（2.84-4.86％）。种子提取物中的总酚含量从22.23（钾质）到40.88（Dishmook）mg单宁酸当量（TAE）g ^-1DW。总类黄酮含量也获得了类似的趋势。使用三种食物模型系统（包括DPPH，β-胡萝卜素漂白和还原能力）评估了种子提取物的抗氧化活性。在所有模型系统中，Fereydunshahr的种子提取物均比其他种群和BHT（丁基羟基甲苯）具有更高的自由基清除活性。总体而言，从Kohgilooyeh省（Dishmook）收集的Kelussia人群具有较高的酚含量，石油产量和（Z－ligustilide，而从伊斯法罕省（Fereydunshahr和Keloose）收集的种群显示出最高的提取率和抗氧化活性。最后，粘土土壤更适合于单萜类化合物如香芹酚和1，8-桉树脑的生长，而邻苯二甲酸盐如（Z）-ligustilide则更受遗传背景而非环境因素的影响。
