Three types of extracts were prepared using the benefit of variable solvent power of supercritical carbon dioxide under different extraction conditions. The composition and toxicity of CO2 extracts, products of Soxhlet extraction with hexane and ethanol, and essential oils obtained by hydrodistillation were compared. The composition of volatile compounds in the isolates was determined by gas chromatography. The acute toxicity of the isolates was evaluated in Spodoptera littoralis, Musca domestica, Culex quinquefasciatus, and Leptinotarsa decemlineata. The highest acute toxicity was exhibited by essentials oils, followed by CO2 extracts. The lowest LD50 value, 22 g, was measured for savory essential oil against the larvae of L. decemlineata.
