Abstract: 30 kinds of pesticide residues in wampee were determined rapidly by the method of QuEChERS-LC-MS/MS. In this method, the pesticide residues were extracted from the fruits of Chinese Wampee by shaking with acetonitrile firstly, and then purified by PSA and anhydrous MgSO4, finally the sample solvents were detected by LC-MS/MS. The results showed: the average recovery of 30 pesticides ranged from 56.3% to 109% in the spiked level of 5, 10, 20 μg/kg, with relative standard deviation from 1.0% to 10.7%, and the correlation coefficient of the linear equation can reach 0.996 7 to 0.999 9. This method is simple but with low cost and high efficiency, and can provide reference for multiple pesticides residue in wampee detection tests.

Key words: QuEChERS, LC-MS/MS, Clausena lansium (Lour.) Skeels, pesticide residue
