Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography and ion-trapmass spectrometry has been used to identify biogenic volatile organic compounds present in theheadspace of chopped leaves of Eucalyptus (E.) dunnii, E. citriodora, and E. saligna. A simple HS-SPME method entailing 30 min of extraction at 30 
C was developed for this purpose. Thirtycompounds were identified in the headspace of 60 juvenile chopped Eucalyptus leaves, and another30 were tentatively identified. The presence of compounds such as (E)-4,8-dimethyl-1,3,7-nonatriene(DMNT), (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene (TMNT), (E,E)-
