| Abstract: | A new,rapid,and efficient method,multiple reaction monitoring liquid chromatography-tandem mass spectrometry,has been developed for analysis of Bupirimate in cucumber and soil.The sample was extracted with acetonitrile and cleaned by soild phase extraction（SPE）cartridge.The mass spectrometer was operaed with electrospray in positive ion mode（ESI＋）.The target analytes were quantified by external standard method.Average recoveries of Bupirimate in cucumber and soil samples were in the range of 93.69～104.93% at three spiking levels.with a RSD between 3.42% and 7.47%.The quantitative detection limit of this method was 0.001 6mg/kg.In the concentration range of 5-320ng/mL.Bupirimate displayed a good linearity with peak area,with a correlation coefficient（R）higher than 0.999.The method is suitable for the routine and confirmation analysis on cucumber and soil. |
