The present study deals with the extraction of 33 pesticide residues belonging to five different groups of pesticides: CHs, OP pesticides, pyrethroids, carbamates and the miscellaneous pesticides (Table 1), from P. anisum using two different extraction methods followed by Florisil column cleanup. Both methods are multiclass multiresidue methods that are reported in the Pesticide Analytical Manual (PAM) of the FDA, and also in the Official Methods of Analysis of the AOAC.
