Resumo: Essential oils obtained from the flowers of Dendropanax morbifera were extracted and the chemical composition and larvicidal effects were studied. The analyses were conducted by gas chromatography and mass spectroscopy (GC-MS) revealed that the essential oil of D. morbifera contained 27 compounds. The major chemical components identified were gamma-elemene (18.59%), tetramethyltricyclohydrocarbon (10.82%), beta-selinene (10.41%), alpha-zingibirene (10.52%), 2-isopropyl-5-methylbicylodecen (4.2%), beta-cubebene (4.19), and 2,6-bis(1,1-Dimethylethyl)-4-phenol (4.01%). The essential oil had a significant toxic effect against early fourth-stage larvae of Aedes aegypti L with an LC(50) value of 62.32 ppm and an LC(90) value of 131.21 ppm. The results could be useful in search for newer, safer, and more effective natural larvicidal agents against A. aegypti. (C) 2009 Elsevier Ltd. All rights reserved.
