A method has been developed for the simultaneous determination of four plant growth regulators (PGRs) residues in soybean sprouts and mung bean sprouts. The sample preparation procedure was based on a QuEChERS method. The method showed excellent linearity (r2≥ 0.9985) and precision (RSDs ≤ 13.0 %). Average recoveries of four PGRs ranged between 74.9 % and 106.3 % at spiking levels 0.05, 0.5 and 1 mg kg−1. The LODs and LOQs were in the ranges of 0.27–9.3 μg kg−1and 0.90–31 μg kg−1, respectively. The procedure was applied to 18 bean sprout samples, and benzyladenine was found in some of the analyzed samples.
