ABSTRACT
AIM:
To study a method for the determination of 13 N-methylcarbamate peticides in traditional Chinese herbal medicines(TCHMs).METHODS:
Thirteen pesticides were extracted by acetonitrile,and purified through solid phase extraction(SPE)cartridges,then detected by HPLC with post-column derivatization and Fluorescense Detector excited wavelength was 330 nm,emissive wavelength was 465 nm.RESULTS:
The analytical performance was demonstrated by the analysis of 6 TCHMs samples' extracts,spiked at three concentration levels for each pesticide.In general,the recoveries ranging from 74.1 to 108.8%,with relative standard deviations(RSDs)better than 15%,were obtained.The limit of quantification(LOD)of 13 pesticides from 0.000 3 to 0.06 mg/kg.CONCLUSION:
The method has good extraction efficiency and purification effect,which could be standard of N-methylcarbamate peticides residues in the routine analysis of TCMs.
