| Summary: | A simple, sensitive, and rapid multi-residue analytical method was developed based on gas chromatography-tandem mass spectrometry (GC–MS/MS) and used to determine 77 multiclass pesticides in red ginseng. Samples were extracted and purified via a modified QuEChERS method. The calibration curves were in the range of 5 to 200 ng mL<sup>−1</sup>. The limits of detection (LODs) of the method were from 0.08 to 4.0 μg kg<sup>−1</sup> and limits of quantification (LOQs) were in the range of 0.2–12.0 μg kg<sup>−1</sup>. The average recoveries of the method ranged from 61% to 133.9% at two spiked levels of 20 and 100 μg kg<sup>−1</sup> in red ginseng samples, with relative standard deviations (RSDs) of 0.2% to 14.9%. |
