Insecticide Activity of Peppermint and Lavender Extracts Isolated by Different Methods

Popis výsledku v původním jazyce

Biologically active components were isolated from peppermint (Mentha piperita L.) and lavender (Lavandula angustifolia L.) using the supercritical fluid extraction (SFE). Three types of SFE extracts were prepared under different experimental conditions and compared in terms of chemical composition and biological activity with the products of hydrodistillation and Soxhlet extraction with ethanol and hexane. The composition of volatile oil in all extracts was determined using GC-MS and GC-FID. Insecticideactivity of all isolates was determined in terms of toxicologic (LD50) and antifeedant effects against model kinds of insects. The efficiency of SFE extracts was comparable with that of hydrodistillate and higher than the efficiency of other extracts. On the basis of LD50 values, the peppermint isolates showed specific effect on adults of Leptinotarsa decemlineata in contrary to lavender extracts which were more effective against Musca domestica adults and Spodoptera litoralis larvae.
