| Abstract: | Objective] In order to systematically study the residues of avermectins in fresh fruit of Lycium barbarum L. and promote the safety production. Method] the residues of avermectins in fresh fruit of Lycium barbarum L. were detected using the high performance liquid chromatography （HPLC） method and a test for the residue of avermectins in fresh fruit of Lycium barbarum L. was conducted. The derivative three fluorine acetic anhydride and N methyl imidazole were extracted from Chinese wolfberry fruit samples using acetonitrile and detected by high performance liquid chromatography with fluorescence detector and quantified by the external standard method. Result] The results showed that the limit of detection of the method was 2.0 x 10-3 mg/kg and the average recovery rate of the method varied from 100% to 107.9% with the relative standard deviation ranging from 1.9% to 7.9%. Furthermore, the residue test indicated that the residue of avermectins decreased with the time prolonged and the curve of degradation dynamics followed the first-order kinetics equation and the degradation was fast. |
