[Application of adsorption chromatography to the colorimetric determination of urinary estrogens in late pregnancy (author's transl)].
A new extraction procedure of urinary estrogens, based upon adsorption chromatography on Amberlite XAD-2, was deviced for a selective and complete extraction of these components. Estrogens were then quantified, without preliminar hydrolysis, by the colorimetric Kober reaction, modified by Ittrich. The reliability of this method has been established by comparison with four other methods.
