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.］
