A　method　based　on　reversed-phase　liquid　chromatography-tandem　mass　spectrometry　(LC/MS/MS)　coupled　with　solid　phase　extraction　(SPE)　was　developed　and　validated　for　qualitative　and　quantitative　detection　of　eight　parabens　in　four　types　of　food　simulant　sample,　including　distilled　water,　3%　acetic　acid,　10%　ethanol　and　olive　oil.　The　detection　limits　of　the　eight　parabens　after　the　SPE　procedure　were　in　the　range　of　0.005-0.010　mu　g　L-1　in　distilled　water,　0.006-0.015　mu　g　L-1　in　3%　acetic　acid,　0.005-0.017　mu　g　L-1　in　10%　ethanol　and　0.2-0.6　mu　g　L-1　in　olive　oil.　The　relative　standard　deviations　(RSDs)　were　in　the　range　of　1.90-8.48%　for　distilled　water,　1.01-3.73%　for　3%　acetic　acid,　5.78-12.97%　for　10%　ethanol　and　0.29-5.40%　for　olive　oil.　The　proposed　method　was　applied　to　assess　the　migration　of　parabens　from　real　antibacterial　plastic　packaging　samples　with　satisfactory　results.
