ZUSAMMENFASSUNG

The optimal conditions for the isolation of esfenvalerate from the biological specimens have been determined. It was shown that this compound can be separated from the endogenous component of a biological material by means of liquid-liquid extraction and chromatography on a L 40/100 mcm silica gel column. The identification and quantitative analysis of esfenvalerate extracted from cadaveric liver and blood can be accomplished with the use of thin layer chromatography, UV and IR spectrophotometry as well as chromatomass spectrometry.
