AB  - A method was developed for the determination of four insecticide residues in 
      honey and royal jelly by gas chromatography-negative chemical ionization mass 
      spectrometry (GC-NCI/MS). The honey and royal jelly samples were treated with 
      different preparation methods as the result of the different components. The 
      honey sample was extracted with ethyl acetate and cleaned up with primary second 
      amine, and the royal jelly sample was extracted with acetonitrile-water (1:1, 
      v/v), and cleaned up with a C18 solid-phase extraction column. Finally, the 
      extracts of the honey and royal jelly were analyzed by GC-NCI/MS in selected ion 
      monitoring (SIM) mode separately. External standard calibration method was used 
      for quantification. The linearities of calibration curves of the four 
      insecticides were good with the correlation coefficients greater than 0.99 in the 
      range of 50-500 microg/L. The limits of the detection (LODs) of the four 
      insecticides were in the range of 0.12- 5.0 microg/kg, and the limits of the 
      quantification (LOQs) were in the range of 0.40-16.5 microg/kg. The recoveries of 
      the four insecticides spiked in honey and royal jelly at three spiked levels (10, 
      15 and 20 microg/kg) were in the range of 78.2 -110.0%, and the relative standard 
      deviations (RSDs) were all below 14%. The sensitivity and selectivity of this 
      method were good with no interfering peaks. The proposed method is simple quick 
      and effective to analyze the four insecticide residues in honey and royal jelly.
