title: Development of a method for the analysis of four plant growth regulators (PGRs) residues in soybean sprouts and mung bean sprouts by liquid chromatography-tandem mass spectrometry.
abstract: 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 (r(2) ≥ 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(-1) and 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.
