| Abstract: | A rapid, specific and sensitive multiresidue method based on dispersive solid phase extraction sample preparation and gas chromatography with the mass spectrometric detection for the analysis of 234 pesticides in Korean herbs (Acanthopanax senticosus, Morus alba L., Hovenia dulcis) has been developed. Method recoveries were found to be between 62 and 119% with relative standard deviation lower than 21% for all compounds in the concentration range of 0.05 to 0.400 mg kg? 1. Limits of quantification of most compounds are below 0.050 mg kg? 1. The data demonstrate that this method was successfully used for analysis of 234 pesticides in Korean herbs. |
