Abstract
THE numerous paper chromatographic methods1–3 so far presented for the separation of corticosteroids all have limitations; our results may therefore be of interest. We have found that by impregnating the papers with a 90 per cent methanol solution we could separate the corticosteroids rapidly at room temperature (16–20°C.). The method also works for prednisone and prednisolone (Table 1). Furthermore, it is suitable for quantitative and semi-quantitative determinations.
