Abstract

The volatile leaf oils of Eucalyptus cylindriflora Maiden and Blakely, E. erythronema Turcz var. erythronema, E. erythronema Turcz var. marginata (Benth.) Domin, E. dielsii C.A. Gardner, E. stricklandii Maiden, E. carnei C.A. Gardner, E. kruseana F. Muell., E. brachyphylla C.A. Gardner, E. ewartiana Maiden, E. orbifolia F. Muell., E. websteriana Maiden, E. crucis Maiden subsp. crucis, E. caesia Benth. subsp. caesia and E. caesia, Benth. subsp. magna Brooker and Hopper, isolated by vacuum distillation, were analysed by GC-MS and by GC. All species contained α-pinene (5.1–49.6%), 1,8-cineole (4.2–75.1%), p-cymene (0.2–23.5%) and aromadendrene/terpinen-4-ol (0–26.8%) as principal leaf oil components.
