A　method　based　on　reversed-phase　liquid　chromatography-tandem　mass　spectrometry　(LC/MS/MS)　combined　with　solid　phase　extraction　(SPE)　was　developed　and　validated　for　qualitative　and　quantitative　detection　of　eight　parabens　in　three　types　of　water-based　food　simulants　including　distilled　water,　3%　acetic　acid,　10%　alcohol.　Detection　limits　of　eight　parabens　after　SPE　procedure　were　0.005-0.010　mu　g/L　in　distilled　water,　0.006-0.015　mu　g/L　in　3%　acetic　acid　and　0.005-0.017　mu　g/L　in　10%　alcohol.　The　relative　standard　deviations　(RSDs)　were　in　the　range　of　1.90-8.48%　for　distilled　wsater,　1.01-3.73%　for　3%　acetic　acid　and　5.78-12.97%　for　10%　alcohol.　The　method　could　make　a　complement　for　detecting　parabens　migrated　to　food　and　feeds.
