AB  - A method based on the cleaning effects of different sorbents and gas 
      chromatography-triple quadrupole mass spectrometry (GC-QQQ-MS/MS) was developed 
      for the determination of 18 polychlorinated biphenyls (PCBs) in camellia seeds. 
      The camellia seeds were extracted with acetonitrile, salted out with sodium 
      chloride, then cleaned-up by QuEChERS with anhydrous MgSO(4), C18, primary 
      secondary amine (PSA), and multi walled carbon nanotubes (NANO) using multiple 
      vortex after the centrifugal separation, and finally analyzed by GC-QQQ-MS/MS in 
      multiple reaction monitoring mode via positive electrospray ionization. All the 
      18 PCBs could be completely separated with an excellent linear relationship. The 
      limits of detection for the 18 PCBs were 5 mug/kg. For all the samples, the mean 
      spiked recoveries was 109.2% with relative standard deviations (RSDs) of 
      2.9%-6.2% (n=3). The extraction, purification and analytical methods were 
      developed and assessed. The method was successfully applied to the 48 samples 
      from three main producing provinces of camellia seeds. All the 18 PCBs were not 
      detected from the 48 samples.
