An improved extraction method for plasma steroid hormones.
An easy and rapid column chromatographic method for the extraction of steroid hormones from plasma is presented. It permits the nearly quantitative separation of the steroids in a single step with smaller expenditure of time and work as compared to the usual liquid-liquid extraction. Problems of emulsions are eliminated. Furthermore, fractionated separation of hormones from plasma is possible. A simple procedure for the selective extraction of estriol (isolated from estrone and estradiol) is described.
