摘要 [Objectives] This study was conducted to rapidly qualitatively and quantitatively analyze the residues of 10 plant growth regulators (PGRs) in bean sprouts. [Methods] Using bean sprouts as the test material, a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was established to determine the residual levels of 10 PGRs in bean sprouts. [Results] Under optimized conditions, the retention time of the 10 PGRs ranged from 6.45 to 11.43 min. When the mass concentration ranged from 0.005 to 0.05 μg/ml, all PGRs exhibited good linearity, with correlation coefficients (r)≥0.999 1. The limits of detection (LODs, S/N=3) were in the range of 0.30-0.92 μg/kg, and the limits of quantification (LOQs) were  in the range of 0.50-2.10 μg/kg. The average recovery values at three concentration levels ranged from 80% to 105.8%, with relative standard deviations (RSDs, n=6) of 2.8%-7.5%. [Conclusions] This method is simple and accurate, and provides technical reference for food safety monitoring.
