A method was developed to determine the residue of spirotetramat and its metabolite in various rat organ by ultra performance liquid chromatograph equipped with triple quadrupole mass spectrometer(UPLC-MS/MS).And the distribution and metabolism of spirotetramat in rat were studied.The spirotetramat and metabolite in rat organs were extracted with methanol,cleaned up by solid phase extraction(SPE),and detected by UPLC-MS/MS.The results showed that it took only 3 minutes for sample analysis by MS,and the limi...
