  • Abstract
  • Look Inside

A simple, rapid thin-layer chromatographic method is presented for the detection of barbiturates*2 in blood, serum, or urine in overdose situations. Extraction with ether is followed by evaporation and reconstitution with methanol. Part of the extract is spotted on a 2.5×7.5 cm thin-layer chromatographic plate which is then developed in a mixed solvent system. After drying, the plate is sprayed with N, 2, 6*3-trichloro-p*4-benzoquinone imine and heated. The presence of a barbiturate is indicated by a blue spot. Chromatography in another solvent system assists in the identification of the particular barbiturate*5 ingested.
