Abstract

The volatile leaf oils of Eucalyptus cornuta Labill., E. talyuberlup D. J. Carr & S. G. M. Carr, E. newbeyi D. J. Carr & S. G. M. Carr, E. burdettiana Blakely & Steedman, E. megacornuta C. A. Gardner, E. lehmannii (Schauer) Benth., E. conferruminata D. J. Carr & S. G. M. Carr, E. bakeri Maiden, E. jutsonii Maiden, E. mannensis Boomsma subsp. mannensis,E. leptocalyx Blakely, E. scyphocalyx (F. Muell, ex Benth). Maiden & Blakely, E. platycorys Maiden & Blakely isolated by vacuum distillation, were analysed by GC-MS. Most species contained α-pinene (1.1–46%), 1,8-cineole (0.2–86.1%), aromadendrene/terpinen-4-ol (0–9.5%) and trans-pinocarveol (0.1–13.3%) as principal leaf oil components.
