In order to simplify the pretreatment process in detection of pesticide residues in vegetables and improve the extraction recovery, an ultrahigh pressure technique was adopted in pretreatment experiments on organophosphorus pesticide residues in cabbage, and on the basis of single-factor test, orthogonal pre-conditions were optimized. The results showed that: The optimum process conditions for ultrahigh pressure extraction of dimethoate in cabbage at room temperature are: pressure of 400MPa, extraction solvent volume of 60ml, the holding time of 4min, recovery rate up to 91.3%, compared with the conventional homogenization method, extraction efficiency improved significantly.
