Capillary gas chromatographic determination of phenylpropanolamine in pharmaceutical preparation

The linear calibration curve was obtained with 30-150 μg/ml PPA with detection limit of 6.0 μg/ml. The method was used for the determination of PPA from Sinutab and Tavegyl-D tablets. The relative standard deviation (R.S.D.) for the analysis of pharmaceutical preparation was obtained within 0.4-0.9%.
