Resumo: The heartwood of two specimens of Auxemma glazioviana, collected in two localities of the state of Ceara, Brazil, were submitted to hydrodistillation and their essential oils were characterized by GC-MS. The major components found in the essential oils from Cristais were alpha-bisabolol (sample I, 46.3; sample II, 53.9%) and alpha-cadinol (sample I, 21.1%; sample II, 30.6%), while the essential oils from Quixada were dominated by a-cadinol (sample III, 37.8%) and cadalene (sample IV, 17.9%). The oils from Cristais (samples I and II) were examined with respect to their larvicidal properties against the larvae of a mosquito (Aedes aegypti) and showed LD50 2.98 ppm and 2.53 ppm, respectively.
