Summary A sensitive and simplified method is described for the determination of barbital (B) and pentobarbital (PB) in blood using gas chromatography with a nitrogen-specific flame ionization detector. After a simple one-step extraction, B and PB were reconstituted in trimethylanilinium hydroxide and introduced directly into the gas chromatograph. Lower limits of detection was 0.14 μg/ml for B and PB in either water or blood solutions. The recoveries for B from water and blood were 90 and 88%, respectively; for PB they were essentially complete. The average between-run and within-run coefficients of variation for B from water and blood were lower than 7.8%, whereas those of PB were lower than 3.0%. The scale and sensitivity of detection for B and PB were found to be suitable for use in pharmacokinetic studies in the rat.
