A capillary column gas chromatographic method was developed for the separation and determination of thirteen plasticizers，including dimethyl phthalate acid ester（DMP），diethyl phthalate acid ester（DEP），dipropyl phthalate acid ester（DnPP），diisobutyl phthalate acid ester（DIBP），dibutyl phthalate acid ester（DBP），diamyl phthalate acid ester（DAP），bisphenol A（BPA），di n hexyl phthalate acid ester（DHP），butyl benzyl phthalate acid ester（BBP），di 2 ethylhexyl adipate（DEHA），di（2 ethylhexyl） phthalate acid ester（DEHP），dioctyl phthalate acid ester（DOP） and dinonyl phthalate acid ester（DNP） in plastic packaging materials for foodstuff. The analytes were extracted with hexane from samples by Soxhlet extraction technique，then purified by silica solid phase extraction. Three key factors such as rinse solvent，eluting solvent and eluting volume were optimized. Hexane and toluene（1∶1，by volume） were used as rinse solvents，2 mL ethyl acetate was used as eluting solvent. After filtration，the eluate was determined by gas chromatography with flame ionization detector（GC/FID）. The calibration curves of thirteen plasticizers were linear in the range of 01-1 000 mg/L with detection limits of 0005-0030 mg/L. The spiked recoveries ranged from 90% to 116% with relative standard deviations of 22%-49%. The method was successfully applied in the determination of plasticizers in plastic packaging materials for foodstuff.
