The invention relates to a method for extracting mycotoxins from grain and other food products or from feed and its subsequent quantification. Fields of application are the food industry, the animal feed industry or biotechnology. The objective of the present invention is to develop an extraction method with which it is possible to uniformly extract mycotoxins with different dissolving properties. It was found that with the aid of aqueous, buffered naphthyl and/or phenyl compounds or their heterocyclical analogues, both hydrophobic and hydrophilic mycotoxins can be extracted. The method according to the invention is characterized in that the buffered solutions of naphthyl and/or phenyl compounds and/or their heterocyclical analogues, which carry at least one sulphonic acid or at least one carbonate acid group, are brought into contact with the grain or other food products or animal feed, the aqueous solution is then separated and the content of the extracted mycotoxins in the aqueous solution is determined.
