A simple and efficient method based on solid phase extraction(SPE) cartridge and liquid chromatography-tandem mass spectrometry(LC-MS/MS) was developed for the determination of butylene fipronil residue in bamboo shoots.Samples were extracted with acetonitrile,and the extract was purified with PSA SPE column.The detection of butylene fipronil was performed by LC-MS/MS under multiple reaction-monitoring mode(MRM).Butylene fipronil could be completely separated in 15 min with an excellent linear relationship in the range of 5.0-100.0 μg/L.The detection limit(S/N=3) and quantitation limit for butylene fipronil were 0.21 μg/kg and 0.69 μg/kg，respectively.The recoveries of butylene fipronil at three spiked levels of 4,8,32 μg?kg-1 were in the range of 76%-103% with relative standard deviations of 3.2%-9.9%.Compared with GC and GC-MS method，the proposed method was rapid，sensitive and accurate，and could meet the requirement for the determination of butylene fipronil residue in bamboo shoots.
