ABSTRACT
OBJECTIVE:
To establish a gas chromatography-mass spectrometry (GC-MS) method for detecting 192 pesticides in flos lonicerae. Several bathes of flos lonicerae have been determined in order to find out the current status of pesticide residues in flos lonicerae.METHODS:
The samples were extracted with acetone, and cleaned-up by the combination of gel permeation chromatography (GPC) and solid-phase extraction (SPE), and determined by GC-MS.RESULTS:
The recoveries of most pesticides ranged from 70% to 110% with relative standard deviations (RSDs) ≤15%. The limits of determination were below 0.01 mg·kg-1.CONCLUSION:
This method is sensitive, accurate, and can be used for the determination of multi-residual pesticides in flos lonicerae. Copyright 2012 by the Chinese Pharmaceutical Association.
