Abstract

The volatile leaf oils of Eucalyptus tessellaris F. Muell., E. gummifera (Sol. ex. Gaertner) Hochr., E. bleeseri Blakely, E. umbonata D. Carr & S. Carr, E. lenziana D. Carr & S. Carr, E. hamersleyana D. Carr & S. Carr, E. latifolia F. Muell., E. watsoniana F. Muell. subsp. watsoniana, E. trachyphloia F. Muell., E. maculata Hook., E. citriodora Hook., E. microcorys F. Muell., E. cloeziana F. Muell., E. laevopinea R. T. Baker, E. youmanii Blakely & McKie, E. eugenioides Sieber ex. Sprengel, E. caliginosa Blakely & McKie, E. robusta Smith, E. pellita F. Muell., E. resinifera Smith, E. tintinnans (Blakely & Jacobs) L. A. S. Johnson & K. D. Hill, E. dunnii Maiden, E. bridgesiana R. T. Baker and E. albens Benth., isolated by vacuum distillation, were analysed by GC and GC±MS. Many species contained a-pinene (0.1±64.4%), 1,8-cineole (0.1±70.6%), aromadendrene (0±16.0%), bicyclogermacrene (0±53.8%), globulol (0±8.0%), spathulenol (0±14.0%), b-eudesmol (0±12.7%) and torquatone (0.1±37.4%) as principal leaf oil components.
