(a) Typical gas chromatogram from solid-phase microextraction (SPME) of the volatiles released from a single Eucalyptus tereticornis leaf, confirming 1,8-cineole as the major terpene. This example is from a high-nutrient leaf fed upon by Uraba lugens larvae. The retention time of cineole was approximately 4.60 min. (b) Mass spectra of the cineole peak. The molecular mass of cineole is approximately 154 m/z.|
