To evaluate the chemotaxonomic significance of the essential oils of 23 populations of 18 Iranian Ferula species, the chemical composition of the oils was investigated by GC/FID and GC/MS. Altogether, 84 constituents, representing 81.3-99.7% of the total composition of the oils, have been identified. The composition of six species of the genus, i.e., F. oopoda, F. foetida, F. behboudiana, F. diversivittata, F. galbaniflua, and F. hezarlalehzarica, has been reported for the first time. The main constituents identified were α-terpinyl acetate (73.3%), 2,3,4-trimethylthiophene (2; 49.0%), sabinene (75.3%), verbenone (5; 69.4%), β-pinene (59.0-66.3%), and (Z)-β-ocimene (41.7%). Cluster analysis (CA) of the percentage content of the essential oil components of the Ferula species resulted in the characterization of four groups, i.e., taxa containing either i) monoterpene hydrocarbons, ii) oxygenated monoterpenes, iii) organosulfur compounds, or iv) monoterpene, sesquiterpene, and aliphatic hydrocarbons as the principal classes of compounds. Based on the results obtained, the chemical independence of F. hirtella from F. szowitsiana and of F. galbaniflua from F. gummosa at the specific level was concluded and their positions as distinct species were confirmed. The chemotaxonomic relationships among the representatives of the genus Ferula have been discussed in detail.
为了评估 18 种伊朗 Ferula 物种的 23 个种群的精油的化学分类学意义，通过 GC/FID 和 GC/MS 研究了油的化学成分。总共鉴定出了 84 种成分，占油总组成的 81.3-99.7%。该属的六种物种，即 F. oopoda、F. foetida、F. behboudiana、F. diversivittata、F. galbaniflua 和 F. hezarlalehzarica 的组成首次被报道。鉴定出的主要成分是α-萜品基乙酸酯（73.3%）、2,3,4-三甲基噻吩（2；49.0%）、柠檬烯（75.3%）、马鞭草酮（5；69.4%）、β-蒎烯（59.0-66.3%）和（Z）-β-罗勒烯（41.7%）。对 Ferula 物种精油成分的百分比含量进行聚类分析（CA），结果表明可将其分为四个组，即包含 i）单萜烃、ii）含氧单萜、iii）有机硫化合物或 iv）单萜、倍半萜和脂肪族烃的类化合物作为主要类别的类群。基于所得结果，得出 F. hirtella 在种水平上与 F. szowitsiana 化学上不同，并且 F. galbaniflua 与 F. gummosa 化学上不同的结论，并确认了它们作为不同物种的地位。详细讨论了 Ferula 属代表之间的化学分类学关系。
