Abstract
Ningnanmycin is a novel biochemical pesticide which was now used extensively in China A fast and simple method using highperformance liquid chromatography with ultraviolet detection coupled with solid phase extraction was developed and validated for determination of ningnanmycin in cucumber and soil The recoveries of ningnanmycin from the fortified cucumber and soil samples ranged from 807 to 1077 with relative standard deviations less than 66 Limits of quantification of the method for both cucumber and soil were 002 mg kg−1 The proposed method was successfully applied to determine the dissipation and residues of ningnanmycin in cucumber and soil under field conditions Direct confirmation of the analytes in samples was realized by liquid chromatography–mass spectrometry
