Abstract

) ≥ 0.992. The limits of detection (LODs) and limits of quantification (LOQs) were 0.07-3.41 μg/kg and 0.22-11.36 μg/kg, respectively. The average recoveries of the 21 chemical drugs in oral liquid and health wine were in the range of 61.4%-116.5% and 67.4%-98.4% with the relative standard deviations (RSDs) of 0.2%-13.4% and 0.2%-11.8%, respectively. The developed method is sensitive and reliable. It has been successfully used for the detection of illegally added chemical drugs in real samples.
