Abstract
Chlorinated hydrocarbons, pyrethroids, organophosphorus, and other miscellaneous pesticides in dried and powdered fruits of
Pimpinella anisumwere analyzed using two official Association of Official Analytical Chemists methods as a general guidance, and
applying Florisil column cleanup. Both methods applied proved to show adequate recovery, repeatability and reproducibility for
most of the studied pesticides. But no sole method was able to extract all pesticides residues from real samples. Some pesticides were
not recovered sufficiently from theP. anisumfortified samples. The applied methods were not suitable for the extraction of tet-ramethrin, formothion, pyrazophos and primicarb. Tetramethrin, formothion and pyrazophos showed very low recoveries with the
mentioned methods while primicarb was not recovered at all.
