A high-performance liquid chromatography (HPLC) method has been developed for the assays of five barbiturates in human urine using a new thermoresponsive polymer separation column, which is composed of N-isopropylacrylamide polymer. According to elevating the column temperature from 10 ℃ to 50 ℃, five barbiturates, such as metharbital, primidone, phenobarbital, mephobarbital and pentobarbital, became well separated by this method. Five barbiturates showed good linearity in the range of 0.2-10 mg/ml. Good accuracy, precision and recoveries for these drugs were obtained at 1 and 5 μg/ml urine. The method with the new-type column seems to have high potential to be extensively used in forensic toxicology for analysis of many drugs and poisons by HPLC and HPLC-mass spectrometry (MS) (-MS).
