Abstrakt: This study investigated the seasonal variation (October 2009 to September 2010) in the chemical composition of the leaf essential oil of Ruta graveolens L. and evaluated its activity against third-instar larvae of Aedes aegypti and juvenile nematodes (J2) of Meloidogyne incognita. The essential oil was obtained by hydrodistillation and analyzed by gas chromatography/flame ionization detection (GC/FID) and GC/mass spectrometry (GC/MS). Nine compounds were identified in the oil samples obtained during a year. The major components were 2-undecanone (37.0±2.0% to 58.2±5.1%) and 2-nonanone (17.6±1.3% to 53.1±3.9%). The essential oil showed lc50 and lc90 values of 39.55 and 64.17 ppm for A. aegypti respectively, and 267.20 and 482.03 ppm for M. incognita, respectively. [ABSTRACT FROM AUTHOR]
