      Objective To investigate the residues of plant growth regulators in fruits and vegetables sold in Jilin province. Methods From 2014 to 2017, multiple fruit and vegetable samples were collected from 9 regions of Jilin province. According to the National food pollutant and harmful factors risk monitoring manual from 2014 to 2017, the samples were detected by ultra performance liquid chromatography-tandem mass spectrometry and gas chromatography-tandem mass spectrometry. Results Twelve kinds of plant growth regulators were detected in the samples collected from 2014 to 2017, and the species detection rate reached 57.1%. Plant growth regulators were detected in 117 samples, and the detection rate reached 36.9%. Conclusion There are certain food safety problems in the residues of plant growth regulators of fruit and vegetable sold in Jilin province, and corresponding measures should be taken to improve food safety.
