Abstract

The volatile leaf oils of Eucalyptus oleosa F. Muell. ex Miq., E. kochii Maiden and Blakely, E. horistes L.A.S. Johnson & K.D. Hill, E. eremicola Boomsma, E. peeneri (Blakely) Prior & Johnson ex Boomsma, E. flocktoniae (Maiden) Maiden, E. transcontinentalis Maiden, E. socialis F. Muell. ex Miq., E. gillii Maiden, E. yumbarrana Boomsma and E. yalatensis Boomsma, isolated by vacuum distillation, were analysed by GC-MS. Most species contained β-pinene (8-29%), β-pinene (0.2-21%), 1,8-cineole (3-88%), p-cymene (0.4-3%), aromadendrene (0.1-8%) and trans-pinocarveol (0.3-8%) as principal leaf oil components.
