High performance liquid chromatography ( HPLC) combined with gel permeation chromatogra-phy ( GPC ) method was established to determine fifteen kinds of polycyclic aromatic hydrocarbons ( PAHs) contents of oil-tea camellia seed oil. The results showed that the calibration curves of fifteen kinds of PAHs were correlated well with their contents in each linear range, and all the correlation coeffi-cients were over 0. 999 0. Meanwhile, the limit of detection, recovery of standard addition and standard deviation were in the range of 0. 05-0. 20 μg/kg,78. 21% -95. 64% and 1. 39% -4. 55%, respec-tively. The method had items of simpliness, accuracy and high efficiency, which was suitable for PAHs detection of oil-tea camellia seed oil in large quantities.
