OBJECTIVE To develop GC/MS method in detect plasticizers in compound aluminum hydroxide tablets adsorbed from pharmaceutical packaging. METHODS The column： HP-5MS silica capillary column (30 m×0.25 μm，0.25 mm) was used； Ion source temperature was 230 ℃； Quadrupole temperature was 150 ℃； The total ion scanning rang： m/z 50～500. RESULTS The diethylhexyl phthafate linearity was in the range of 0.5-20.0 μg·mL-1 with a regression coefficient of 0.999 0. The average recovery of this method was 98.8%， and RSD was 1.4%. The RSD of intra-day and inter-day was 2.8% and 3.7% respectively. CONCLUSION This method is specificity， sensitive， and can be applied to detect and research DEHP which may be adsorbed or penetrated into drugs.
