The chemical compositions of 20 Algerian Daucus gracilis essential oils were investigated using GC-FID, GC/MS, and NMR analyses. Altogether, 47 compounds were identified, accounting for 90 - 99% of the total oil compositions. The main components were linalool (18; 12.5 - 22.6%), 2-methylbutyl 2-methylbutyrate (20; 9.2 - 20.2%), 2-methylbutyl isobutyrate (10; 4.2 - 12.2%), ammimajane (47; 2.6 - 37.1%), (E)-β-ocimene (15; 0.2 - 12.8%) and 3-methylbutyl isovalerate (19; 3.3 - 9.6%). The chemical composition of the essential oils obtained from separate organs was also studied. GC and GC/MS analysis of D. gracilis leaves and flowers allowed identifying 47 compounds, amounting to 92.3% and 94.1% of total oil composition, respectively. GC and GC/MS analysis of D. gracilis leaf and flower oils allowed identifying linalool (22.7%), 2-methylbutyl 2-methylbutyrate (18.9%), 2-methylbutyl isovalerate (13.6%), ammimajane (10.4%), 3-methylbutyl isovalerate (10.3%), (E)-β-ocimene (8.4%) and isopentyl 2-methylbutyrate (8.1%) as main components. The chemical variability of the Algerian oil samples was studied using statistical analysis, which allowed the discrimination of three main Groups. A direct correlation between the altitudes, nature of soils and the chemical compositions of the D. gracilis essential oils was evidenced.
采用气相色谱 - 氢火焰离子化检测器（GC - FID）、气相色谱 - 质谱联用仪（GC/MS）和核磁共振（NMR）分析方法，对20种阿尔及利亚细叶胡萝卜籽精油的化学成分进行了研究。共鉴定出47种化合物，占精油总成分的90 - 99%。主要成分有芳樟醇（18；12.5 - 22.6%）、2 - 甲基丁基2 - 甲基丁酸酯（20；9.2 - 20.2%）、2 - 甲基丁基异丁酸酯（10；4.2 - 12.2%）、阿米马詹（47；2.6 - 37.1%）、（E）-β-罗勒烯（15；0.2 - 12.8%）和3 - 甲基丁基异戊酸酯（19；3.3 - 9.6%）。还对从不同器官获得的精油的化学成分进行了研究。对细叶胡萝卜籽叶和花进行GC和GC/MS分析，分别鉴定出47种化合物，占精油总成分的92.3%和94.1%。对细叶胡萝卜籽叶油和花油进行GC和GC/MS分析，鉴定出芳樟醇（22.7%）、2 - 甲基丁基2 - 甲基丁酸酯（18.9%）、2 - 甲基丁基异戊酸酯（13.6%）、阿米马詹（10.4%）、3 - 甲基丁基异戊酸酯（10.3%）、（E）-β-罗勒烯（8.%).和异戊基2 - 甲基丁酸酯（8.1%）为主要成分。利用统计分析方法研究了阿尔及利亚油样的化学变异性，从而区分出三个主要类别。结果表明，海拔高度、土壤性质与细叶胡萝卜籽精油的化学成分之间存在直接相关性。
