Abstract

The volatile leaf oils of Eucalyptus yilgarnensis (Maiden) Brooker, E. gracilis F. Muell., E. quadrans Brooker & Hopper, E. calygocona Turcz. var. calygocona, E. celastroides Turcz subsp. celastroides, E. celastroides Turcz. subsp. virella Brooker. E. myriadena Brooker, E. aequioperta Brooker & Hopper, E. cylindrocarpa Blakely, E. ovularis Maiden & Blakely, E. cyclostoma Brooker, E. rigens Brooker & Hopper, E. famelica Brooker & Hopper, E. striaticalyx W. Fitzg. subsp. striaticalyx, E. striaticalyx W. Fitzg. subsp. gypsophila D. Nicolle, E. striaticalyx W. Fitzg. subsp. beadellii D. Nicolle, E. striaticalyx W. Fitzg. subsp. canescens D. Nicolle, E. ‘species U’, E. ‘aff. pileata’ (Eyre Peninsular form), isolated by vacuum distillation, were analysed by GC and by GC–MS. Many species contained α-pinene (0.08–33.1%), limonene (0–3.6%), 1,8-cineole (2.6–86.1%), p-cymene (0.3–14.2%), pinocarvone (0–9.0%), aromadendrene (0–29.9%), allo-aromadendrene (0–2.5%), trans-pinocarveol (0–22.0%), globulol (0.07–6.6%), spathulenol (0.07–8.0%) and torquatone (0.06–3.0%) as principal leaf oil components. © 1997 John Wiley & Sons, Ltd.
