Hydrodistillation of the dried leaves of 13 species of the genus Eucalyptus L' Hér., viz., E. bicostata Maiden, Blakely & Simmonds, E. cinerea F. Muell. ex Benth., E. exerta F. Muell., E. gigantea Hook. f., E. gunnii Hook. f., E. macarthurii Deane & Maiden., E. macrorrhyncha F. Muell., E. maidenii F. Muell., E. odorata Behr., E. pauciflora Sieber ex Sprengel, E. sideroxylon A. Cunn. ex Woolls, E. tereticornis Sm., and E. viminalis Labill., harvested from Souinet arboreta (region of Ain Draaham, north of Tunisia) in June 2006, afforded essential oils in yields varying from 0.5+/-0.2 to 3.9+/-0.4%, dependent on the species. E. cinerea and E. exerta provided the highest and the lowest percentage of essential oil amongst all the species examined, respectively. Analysis by GC (RI) and GC/MS allowed the identification of 142 components, representing 81.5 to 98.9% of the total oil. The contents of the different samples varied according to the species. The main components were 1,8-cineole (1), followed by cryptone, spathulenol (4), p-cymene (2), viridiflorol (6), globulol (7), beta-eudesmol, alpha-terpineol (5), limonene (8), D-piperitone, alpha-pinene (3), cuminal, and gamma-eudesmol. The principal component and the hierarchical cluster analyses separated the 13 Eucalyptus leaf essential oils into three groups, each constituting a chemotype.
从 2006 年 6 月在突尼斯北部 Ain Draaham 地区的 Souinet 树木园采集的 13 种桉树属植物（Eucalyptus L' Hér.）的干叶中，通过水蒸馏法获得了精油，产量从 0.5+/-0.2 到 3.9+/-0.4%不等，具体取决于物种。在所有被研究的物种中，E. cinerea 和 E. exerta 分别提供了最高和最低百分比的精油。通过 GC（RI）和 GC/MS 分析鉴定出了 142 种成分，占总油的 81.5%至 98.9%。不同样品的含量因物种而异。主要成分是 1,8-桉树脑（1），其次是隐酮、石竹烯醇（4）、对伞花烃（2）、香叶醇（6）、愈创木醇（7）、β-桉叶醇、α-松油醇（5）、柠檬烯、D-对薄荷酮、α-蒎烯、香茅醇和γ-桉叶醇。主成分和层次聚类分析将 13 种桉树叶精油分为三组，每组构成一种化学型。
