A simple method was established to detect the fatty acid alkyl esters （FAAEs） in olive oil using the commercial silica gel solid phase extraction column to purify the olive oil, and gas chromatography - mass spectrometry （ GC - MS） as the detector. The FAAEs were well separated and detected. The detection limits were 1.0 mg/kg, and the average recoveries were in the range of 99.05% -111.13% with the relative standard deviations （RSDs） in the range of 0.50% -6.70%. This method could be used for the determination of different grades of olive oils, and provide technical support for the identification of adulteration of extra virgin olive oil.
