Components of commercial pyrabital preparations were determined by gas chromatography. The stationary phase used was 1.5% and 20% SE-30 (Chromosorb-W, 60-80 mesh), and determination of pyrabital and acetophenetidine was carried out by the conditions given in Fig. 1. Bromvalerylurea was determined by programmed-temperature gas chromatography, and caffeine was determined after removal of the co-existing acetophenetidine by extraction. Determination was made by the absolute calibration method and by internal standard method. Standard deviation was within 2.62%.
