This European Standard specifies methods for the extraction and clean-up of food samples of plant origin for quantitative determination of pesticide residues. Different solvents can be used for this purpose. These pesticide residues are generally associated with other co-extracted compounds which would interfere in the analysis. To purify the crude extracts to be analysed, several techniques can be used. This European Standard contains the following extraction and clean-up methods that have been subjected to interlaboratory studies and/or are adopted throughout Europe: - method M: Extraction with acetone and liquid-liquid partition with dichloromethane/light petroleum, if necessary clean-up on FlorisilĀ® ) [1], [2], [3]; - method N: Extraction with acetone, liquid-liquid partition with dichloromethane or cyclohexane/ethyl acetate and clean-up with gel permeation and silica gel chromatography [4], [5]; - method P: Extraction with ethyl acetate, and if necessary, clean-up by gel permeation chromatography [6]. This European Standard specifies the details of methods M, N and P for the extraction and the clean-up of food samples of plant origin. Several solvents at different volumes are used for extraction. Techniques of clean-up are listed such as liquid-liquid partition, liquid chromatography on various adsorbents and gel permeation chromatography. A table providing the couples (matrix/pesticide) which have been submitted to collaborative studies and a list of indicative applicability of the method to different pesticides are given for each method, wherever possible.
