Abstract

The volatile leaf oils of Eucalyptus ‘nutans’, E. platypus Hook. var. platypus, E. platypus Hook. var. heterophylla Blakely, E. spathulata Hook. subsp. spathulata, E. spathulata Hook. subsp. grandiflora (Benth.) L.A.S. Johnson and D.F. Blaxell, E. steedmanii C.A. Gardner, E. eremophila (Diels) Maiden subsp. eremophila, E. salubris F. Muell. subsp. salubris, E. ravida L.A.S. Johnson and K.D. Hill, E. campaspe S. Moore, E. diptera C.R.P. Andrews, E. terebra L.A.S. Johnson and K.D. Hill, E. doratoxylon F. Muell., and E. decurva F. Muell, isolated by vacuum distillation, were analysed by GC and by GC-MS. All species contained α-pinene (2.8–32.5%), 1,8-cineole (8.2–51.2%), p-cymene (0.3–3.3%) and aromadendrene (2.3–19.0%) and bicyclogermacrene (0.3–28.6%) as principal leaf oil components.
