Download or read book Modern Methods of Steroid Analysis written by Erich Heftmann and published by Elsevier. This book was released on 2012-12-02 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Gas Phase Chromatography of Steroids written by Kristen B. Eik-Nes and published by Springer. This book was released on 2012-05-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few fields have advanced faster over the past quinquennium than separation and estimation of steroids by the technique of gas phase chromatography. A detailed and complete review of this topic would therefore be beyond the scope of the authors contributing to this monograph. It was, however, felt that a discussion of some of the highlights of this rapid advance might be of help for laboratories estimating steroids in biological samples. One of the difficulties in producing a monograph of this kind is that before it can appear in print it is likely that some of the methods it discusses will have been overtaken by better methods, so swiftly is progress now made. No editorial power has been exercised in trying to make a uni form account of technology in this field, and the idiosyncrasies of each individual author have been left intact. Through this approach we hope that what has been lost in scholarly appearance is regained in general appeal.

Download or read book Chromatographic Methods in Clinical Chemistry and Toxicology written by Roger Bertholf and published by John Wiley & Sons. This book was released on 2007-01-30 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to fill the gap that exists between theoretical treatments of chromatography, and clinical chemistry and toxicology texts, which focus almost exclusively on clinical relevance and applications. Chromatography has a vast array of clinical applications, and though the chromatographic methods were first introduced decades ago, new applications of this technology are being used to explore previously inaccessible frontiers in clinical diagnostics and toxicological testing. An up-to-date book devoted to clinical and toxicological applications of chromatographic methods will serve as an instructional and reference text, useful to students, laboratory technicians, and researchers.

Download or read book Thin Layer Chromatography in Drug Analysis written by Lukasz Komsta and published by CRC Press. This book was released on 2013-12-20 with total page 1070 pages. Available in PDF, EPUB and Kindle. Book excerpt: Used routinely in drug control laboratories, forensic laboratories, and as a research tool, thin layer chromatography (TLC) plays an important role in pharmaceutical drug analyses. It requires less complicated or expensive equipment than other techniques, and has the ability to be performed under field conditions. Filling the need for an up-to-date, complete reference, Thin Layer Chromatography in Drug Analysis covers the most important methods in pharmaceutical applications of TLC, namely, analysis of bulk drug material and pharmaceutical formulations, degradation studies, analysis of biological samples, optimization of the separation of drug classes, and lipophilicity estimation. The book is divided into two parts. Part I is devoted to general topics related to TLC in the context of drug analysis, including the chemical basis of TLC, sample pleparation, the optimization of layers and mobile phases, detection and quantification, analysis of ionic compounds, and separation and analysis of chiral substances. The text addresses the newest advances in TLC instrumentation, two-dimensional TLC, quantification by slit scanning densitometry and image analysis, statistical processing of data, and various detection and identification methods. It also describes the use of TLC for solving a key issue in the drug market—the presence of substandard and counterfeit pharmaceutical products. Part II provides an in-depth overview of a wide range of TLC applications for separation and analysis of particular drug groups. Each chapter contains an introduction about the structures and medicinal actions of the described substances and a literature review of their TLC analysis. A useful resource for chromatographers, pharmacists, analytical chemists, students, and R&D, clinical, and forensic laboratories, this book can be utilized as a manual, reference, and teaching source.

Download or read book Analysis of Sterols written by J. Goad and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it Samuel Johnson, 18 April, 1775* Sterols are among the most studied groups of natural products with interest commencing in the 19th century and running to the present. Investigations have embraced the refinement of separation procedures, the development of new analytical techniques and instrumentation for structure elucidation, the unravelling of biosynthetic mechanisms, the determination of the physiological functions of sterols, and the role they play in health and disease. In the past 20-30 years interest in the medical implications of sterol biochemistry, studies on the sterols of plants, algae and fungi, and the identification of the many unusual sterols from marine organisms have proceeded in parallel and somewhat independently. Although the motiva tion and goals for the various lines of investigation have differed widely the researchers working in each of these areas have contributed a wealth of knowledge to the literature relating to the analysis of sterols and many diverse new sterols have been discovered. We conceived this book as a modest attempt to bring together some of this literature in the hope that it may be helpful to newcomers to sterol research. We had originally intended to produce a 'handbook' outlining in detail the protocols to be followed for sterol extraction, chromatography, NMR analysis, etc. in order to identify the components of a sterol mixture.
