Abstract

Essential oils were extracted from leaves of eight taxa of the genus Angophora, and then analysed. As expected the individual components of these oils were essentially the same as those found in the Eucalyptus species of ourearlier studies (Bignell et al,, 1997b, Flavour Fragrance J. 12, 423-432). In addition, as is also the case with the bloodwood eucalypts, only relatively low yields of oil were obtained. In all cases the Cineole component was extremely small, but the oils of six of the eight contained very large concentrations of the sesquiterpene Bicyclogermacrene. A table of the 52 major oil components is included. Principal components analysis (PCA) was performed on the gas chromatograms (GC) of the essential oils and the resulting scores plots compared with the cladistic classification of Thiele and Ladiges (1988), Cladistics 4, 23-42), Because of the close relationship between genus Angophora and Eucalyptus 'subgenus' Corymbia, the GC data for the eight Angophora taxa were combined with corresponding data for eleven randomlychosen taxa from 'subgenus' Corymbia (Bignell et al., 1996b, Flavour Fragnance J. 11, 339-347; 1997a, Flavour Fragrance J. 12, 277-284) and a PCA performed on the total system.
