Five pyrethroid pesticide residues for three kinds of traditional Chinese medicines using GC-MS

doi: 10.11833/j.issn.2095-0756.2015.01.016

Abstract: Methods for residual determination by gas chromatography mass spectrometry (GC-MS) of five pyrethroid pesticides in Chrysanthemum morifolium, Atractylodes macrocephala and Cornus officinalis were established. Cloud point extraction-back extraction was used as sample pretreatment method,and PEG 6000 was used as an extraction agent, isooctane was used as a back-extractant, a chromatographic column HP-5MS was used as an analytical column. Content was calculated by the external standard method using GC-MS. Results showed a linear range from 15.00 to 2 000.00 g kg-1 with favorable correlation coefficients (r=0.955-0.999). For the five pyrethroid pesticides, the limit of detection was 0.63-3.10 gkg-1 and quantitation was 2.10-10.31 gkg-1. At spiked concentrations of 50.00-500.00 gkg-1, recoveries ranged from 71.22% to 91.00%. This proposed method can be applied to determine pyrethroid pesticide residues in Chrysanthemum morifolium, A. macrocephala, and Cornus officinalis. [Ch, 4 fig. 4 tab. 19 ref.]
