title: [Determination of progesterone and delta 4-pregnen-20 alpha-ol-3-one contents in ovaries with two-dimensional thin-layer chromatography and spectrofluorimetry].
abstract: The method is developed for quantitative determination of progesterone and delta4-pregnen-20alpha-ol-3-one in ovaries. It includes treatment of the gland homogenate with NaOH, ethylacetate extraction, two-dimensional thin-layer chromatography on silicaged plate Silufol UV254 in benzol-ethylacetate (80:20) and chlorophorm-ethanol (98:2) and the subsequent spectrofluorimetry. For identification of the isolated steroids their chromatographical motility, light absorption, color reactions and fluorescence spectra were studied. The contents of progesterone and delta4-pregnen-20alpha-ol-3 one in the rat ovaries were determined by this method.
