A method for simultaneous detection of multi-mycotoxins in ten kinds of common dried fruits was been exploited by using ultra performance liquid chromatography-tandem mass spectrometry.The edible part of dried fruits was ground up with certain quantity of water.The mash was extracted by 10 mmol/L citric acidacetonitrile,purified by C_(18) column,and filtered using 0.22-μm organic filtration.All the sixteen mycotoxins were well separated in 8 min on ACQUITY UPLC BEH C_(18) column with acetonitrile as phase A and 10 mmol/L ammonium acetate solution containing 0.1% formic acid as mobile phase B.Result showed that the limits of detection(LODs) for the sixteen mycotoxins were 0.01-1.00 μg/L,with linearity range of 1-200 μg/L and correlation coefficients above 0.9981.The average recoveries of the sixteen mycotoxins in ten matrices were 70.48%-118.85%,and the relative standard deviation(RSD,n=6) was 0.3%-11.9%.This economi
