Notes:
A rapid analytical method has been developed to follow the biological oxidation of 17-α-oxy-11-desoxy-corticosterone (Reichstein compound S) to hydrocortisone. Paper chromatography is too slow to follow the progress of a preparative microbiological steroid transformation. However, 17-α-oxy-11-desoxy-corticosterone can be separated in a sufficiently pure state for photometric assay by a simple extraction from fermentation broths containing several steroids. This extraction, coupled with the formation of a sulphuric acid chromogen, permits estimation of the steroid in fermentation liquors. The steady decrease of the 17-α-oxy-11-desoxy-compound thus estimated proved to be a true indication of the progress of the oxidation process, allowing it to be stopped at the most favourable time.
