This is the most comprehensive collection of mass spectral data for steroids available today. It contains some 2,500 newly measured EI(+) mass spectra of androgens and estrogens and their derivatives (trimethylsilyl ethers, O-methyloximes and acetates). Each spectrum is accompanied by the structure, systematic and trivial names, retention index, molecular formula, molar mass, CAS number and sample source of the steroid, with all data obtained using the same mass spectrometer under identical chromatographic and mass spectrometric conditions. Steroids are of considerable therapeutic importance, and the collection will thus be of particular interest to the pharmaceutical industry, as well as an invaluable data source for chemists and biochemists involved in drug development, drug screening and clinical toxicology, endocrinologists, natural products chemists and mass spectroscopists

This book is an essential reference guide to spectroscopic, physical and biological activity data of over 3500 steroid glycosides, offering the structures and the data of the naturally occurring glycosides of steroids. All compounds are arranged according to the structure of the aglycone, and, in its own class, by the increasing molecular weight, making Spectroscopic Data of Steroid Glycosides extremely useful for the structure elucidation of new natural products, particularly glycosides.

Modern Methods of Steroid Analysis reviews modern methods of steroid analysis such as liquid column chromatography, mass spectrometry, and gas chromatography. Topics covered include qualitative and quantitative analysis of plant sterols by gas-liquid chromatography; Raman spectroscopy of steroids; nuclear magnetic resonance; and applications of lanthanide shift reagents. A computerized method for rapid comparison and retrieval of infrared spectral data is also described. This volume is comprised of 22 chapters and begins with an analysis of hormonal steroids using liquid column chromatography, followed by a discussion on the separation of insect molting hormones using high-pressure liquid chromatography. The reader is methodically introduced to the application of gradient elution and thin-layer chromatography to the analysis of corticosteroids and 17-ketosteroids, as well as some aspects of mass spectrometry in steroid analysis. Subsequent chapters explore other methods such as optical rotatory dispersion and circular dichroism, along with radioisotope techniques. In particular, the radioimmunoassay of plasma steroid hormones and plasma aldosterone is considered. This book should be of interest to biochemists.

NMR Data Interpretation Explained shows how to get from an NMR spectrum to a chemical structure through numerous examples and exercises. Each topic is introduced with one or more examples of NMR data accompanied by detailed explanations of the interpretation of that data. Examples are then followed by a number of exercises using detailed images of NMR data. These are followed up by solutions, again with detailed explanations of the step-by-step reasoning used to solve the exercises. --

Interpretation of the Ultraviolet Spectra of Natural Products focuses on the ultraviolet spectrum of chromophores. The book first discusses single chromophores, including absorption due to electron lone pairs in saturated systems and absorption of olefins, alkynes, carbonyl compounds, and thiocarbonyl compounds. The text also takes a look at conjugated chromosomes, such as polyenes, enynes, and conjugated azomethines. The selection also evaluates C-aromatic compounds. Topics include benzenoid and hydrocarbons; phenols and their ethers; styrenes and stilbenes; aromatic carbonyl compounds; and nitro compounds. The text also discusses O- and S- heteroaromatic compounds and N-heteroaromatic compounds. The book highlights the applications of spectrophotometry to the analysis of natural products. Topics include formation of derivatives having absorbing chromophores; reactions leading to changes in absorption of added reagents; and analyses involving transformation to products suitable for spectrophotometry. The text is a good reference for readers wanting to explore chromophores.
