摘要： A method for determination of imidacloprid in Chinese Cabbage was established by using UPLC-MS/MS. and the samples are extracted with acetontrile, and the extract is cleaned up by Florisil SPE cartridges and evaporated. Choromatographic separation was performed on a C18 column,and determined by UPLC-MS/MS.The external standard calibration curves were used for quantification. The results showed that a good linear correlation was obtained in the range of 0.005-0.1ug/mL. The limit of quantif icat ion w as 0. 008 mg/ kg.The average recoveries and the relative standard deviations were in the range of 84.9 %-similar to 92.7 % and 0.9 %similar to 6.2 %, respectively. It is applicable to the determination of imidacloprid redidue in Chinese cabbage.
