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'Her. & E. remota Blakely, isolated by vacuum distillation, were analysed by
gc & by
gc-MS. Many species contained alpha-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%), gamma-eudesmol (0-5.5%), alpha-eudesmol (0-14.8%), beta-eudesmol (0-32.0%) & torquatone (0.1-7.5%) as principal leaf oil components. In several species the beta-triketones agglomerone, tasmanone & lateriticone, together with the terpenoid ketone
jacksonone, were detected at concentrations much greater than 10%.
