The volatile leaf oils of Eucalyptus jacksonii Maiden, E. patens Benth., E. diversifolia Bonpl., E. pachyloma Benth., E. suberea Brooker & Hopper, E. insularis Brooker, E. buprestium F. Muell., E. erectifolia Brooker & Hopper, E. lateritica Brooker & Hopper, E. todtiana F. Muell., E. johnsoniana Brooker & Blaxell, E. exilis Brooker, E. pendens Brooker, E. sepulcralis F. Muell., E. ligulata Brooker, E. aquilina Brooker, E. coronata Gardner, E. preissiana Schauer, E. acies Brooker, E. marginata Donn ex. Smith subsp. marginata, E. marginata Donn ex. Smith subsp. thalassica Brooker & Hopper, E. staeri (Maiden) Kessell & Gardner, E. baxteri (Benth.) Maiden & Blakely ex. J. Black, E. obliqua L'Hér. and E. remota Blakely, isolated by vacuum distillation, were analysed by GC and by GC–MS. Many species contained α‐pinene (0–20.0%), limonene (0–22.2%), 1,8‐cineole (0–62.3%), p‐cymene (0–12.6%), aromadendrene (0–6.4%), allo‐aromadendrene (0–3.7%), bicyclogermacrene (0–21.8%), globulol (0–4.3%), viridiflorol (0–2.5%), spathulenol (0.1–14.2%), γ‐eudesmol (0–5.5%), α‐eudesmol (0–14.8%), β‐eudesmol (0–32.0%) and torquatone (0.1–7.5%) as principal leaf oil components. In several species the β‐triketones agglomerone, tasmanone and lateriticone, together with the terpenoid ketone jacksonone, were detected at concentrations much greater than 10%. © 1997 John Wiley & Sons, Ltd.
