Abstract

The kinetics of decomposition of prednisolone in aqueous solution were studied under anaerobic conditions at 100°C within the pH range 1.8–8.3. At pH=2.5 prednisolone is most stable. Between pH=5.0 and pH=6.0 the decomposition rate is nearly independent of the pH value. The decomposition products, 17-deoxy-21-dehydroprednisolone, 17-deoxyprednisolone, the 17-ketosteroid and the D-homosteroid were analysed quantitatively. The total amount of acidic decomposition products was approximated. Below pH=5.5 prednisolone decomposes to 17-deoxy-21-dehydroprednisolone. However, at higher pH values a mixture of decomposition products appears. All analyses were performed by a stability indicating high performance liquid Chromatographic method using uv detection.
