Gas Chromatography of Steroids

Isotope Effects in Gas-liquid Chromatography of Steroids.

Method for screening urinary steroids by gas chromatography.

Numerous methods are available for measuring urinary steroids in evaluating endocrine dysfunctions. Measurements of these particular steroids, or groups of them, usually involve tedious isolation methods, corrections for interferences and losses of the steroid, and (or) expensive reagents. We show how gas-liquid chromatography provides a rapid, sensitive, and direct method for several steroid m...

Paper Chromatography of Steroids

In Paper I of this series (1) a method was described for the paper chromatographic analysis of certain ketonic steroids as hydrazones formed with Girard’s Reagent T. When that technique was applied to the adrenal cortical hormones, however, certain deficiencies appeared. (a) The RI values of the individual steroid-Reagent T hydrazones were not sufficiently different to permit identification. (b...

The Chromatography of Steroids

significant information in a given field and interpret it in terms of our current knowledge of the rapidly expanding research findings within the life sciences." The preceding publisher's statement is quoted because Dr. Sutton has so admirably carried out his mission. Genes are presented as functional units; specific examples of their fine structure are described with emphasis on their relation...

Paper chromatography of C19 steroids.

The successful use of paper chromatography for t.he separation of corticoids (2) suggested the general usefulness of this procedure for relat,ed compounds. Two procedures for t.he separation of cardiac glycosides and aglycones have been described (3, 1). Preliminary reports (5, G) and a reference (7) have been made on methods for other steroid hormones. This paper describes an effective system ...
