Abstract

The volatile leaf oils of Eucalyptus leptophelba F. Muell., E. patellatis F. Muell., E. distans Brooker, Boland & Kleinig, E. coolabah subsp. coolabah Blakely & Jacobs, E. coolabah subsp. microtheca F. Muell., E. pruinosa Schauer, E. normantonensis Maiden & Cambage, E. lucasii Blakely, E. thozetiana F. Muell. ex. R. Baker, E. moluccana Roxb., E. fibrosa F. Muell, subsp. fibrosa, E. crebra F. Muell., E. drepanophylla F. Muell. ex. Benth., E. staigeriana F. Muell. ex. Bailey, E. conica Deane & Maiden, E. baueriana Schauer, E. caleyi Maiden, E. sideroxylon A. Cunn. ex. Woolls, E. melliodora A. Cunn. ex. Schauer, and E. petraea D. J. Carrr & S. G. M. Carr, isolated by vacuum distilation, were analysed by GC and GC–MS. Many species contained α-pinene (0·1–28·3%), limonene (0–24·1%), 1,8-cineole (0·4–63·2%), p-cymene (0–16·5%), β-caryophyllene (0–15·7%), aromadendrene (0–32·8%), bicyclogermacrene (0–53·8%), globulol (0·1–9·0%) and spathulenol (0·2–21·4%) as principal leaf oil components: all species contained the aromatic ketone torquatone. © 1997 by John Wiley & Sons, Ltd.
