摘　　要：应用超高效液相色谱-串联质谱联用(UPLC-MS/MS)技术,建立了同时检测蔬菜中5种植物生长调节剂的检测方法。样品经乙腈提取,QuEchERS法净化后,Waters HSST_3超高效液相色谱柱分离,方法回收率在73.8%~96.3%之间;相对标准偏差(n=3)范围为1.4%~8.5%。方法检出限范围为1.1×10^(-3)~1.86×10^(-2)mg/kg。The components were extracted with acetonitrile,cleaned up by QuEchERS.The UPLC analyses were performed on an Acquity UPLC HSST_3 column by gradient eluation,the average recoveries of 5 components ranged from 73.8%to 96.3%,and the relative standard deviation were between 1.4% and8.5%,the detection limits of 5 components ranged from 1.1×10^（-3） to 1.86×10^（-2） mg/kg.
