Determination of Pesticide Residues in Zanthoxylum bungeanum Maxim.by Gas Chromatography-Tandem Mass Spectrometry
In this study,gas chromatography-tandem mass spectrometry was used to determine several pesticide residues in Zanthoxylum bungeanum Maxim..The results showed that the linear relationship of 10 pesticides was good in the range of 0.002～0.400 mg·L-1,the correlation coefficient was greater than 0.99.At the same time,the average recovery of 10 pesticides at five different supplemental levels(0.01 mg·kg-1,0.02 mg·kg-1,0.05 mg·kg-1,0.10 mg·kg-1 and 0.20 mg·kg-1)was between 63％and 128％,and the relative standard deviation was 1.2％～9.7％,which met the standard of pesticide residue analysis.The method has the advantages of high accuracy,good precision and wide linear range,which can provide strong support for the detection of pesticide residues in Zanthoxylum bungeanum Maxim.
