AB  - The method for simultaneous determination of four phthalates, namely dimethyl 
      phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP) and di 
      (2-ethylhexyl) phthalate (DEHP) in plastic food-packaging bags by thin layer 
      chromatography (TLC) was developed. The plastic food-packaging bags were 
      extracted with ethanol by ultrasonication, then the mixture was filtrated through 
      membrane (0.45 microm). The mixture of ethyl acetate-anhydrous ether-isooctane (1 
      : 4 : 15, v/v) was used as developing agent on the TLC silica gel plate for 
      development. The filtered liquid was spotted on the TLC plate dealt by acetone, 
      and detected with scanning wavelength of 275 nm and reference wavelength of 340 
      nm. The qualitative analysis of the phthalates was performed using the R(f) 
      values of the chromatogram. The quantitative analysis was performed with external 
      standard method. Good linearities were obtained for DMP, DEP, DBP and DEHP. The 
      detection limits were 2.1 ng for DMP, 2.4 ng for DEP, 3.4 ng for DBP and 4.0 ng 
      for DEHP. The relative standard deviations (RSDs) of the four phthalates were 
      2.8% - 3.5%. The recoveries of the four phthalate standards in real sample were 
      78.58% - 111.04%. The method presented has the advantages of high precision, high 
      sensitivity, small sample size, and simple pretreatment . The method was used to 
      detect the four phthalates in the food-packaging bags. The contents in real 
      samples were close to the results by gas chromatography.
