    Insecticide Activity of Herb Extracts Isolated by Different Methods

  • Original language description

    The aim of this study was to compare the insecticidal activity of extracts obtained by SFE and traditional extraction method. Three types of extracts were prepared using the benefit of variable solvent power of supercritical carbon dioxide under different experimental conditions. Composition and product activities of the CO2 extracts were compared with hydrodistillation (HD) and Soxhlet extraction. The composition of volatile compounds in the isolates was determined by gas chromatography, and the toxicity and antifeedant effects of the extracts on larvae of Colorado potato beetle were evaluated.

    Insekticidní aktivita rostlinných extraktů izolovaných různými metodami

  • Czech description

    Cílem studia bylo porovnat insekticidní aktivitu extraktů získaných SFE a tradičními extrakčními metodami. Vzhledem k možnosti nastavení rozpouštěcí schopnosti oxidu uhličitého změnou extrakčních podmínek byly připraveny tři typy extraktů. Bylo provedenoporovnání složení a aktivity CO2-extraktů s produkty získanými hydrodestilací (HD) a Soxhletovou extrakcí. U všech izolátů bylo stanoveno složení těkavých látek plynovou chromatografií a vyhodnocena jejich toxicita a protipožerové účinky na larvy mandelinky bramborové.
