Download or read book Mass Spectrometry written by James M. Thompson and published by CRC Press. This book was released on 2017-12-22 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that there are about 10 million organic chemicals known, and about 100,000 new organic compounds are produced each year. Some of these new chemicals are made in the laboratory and some are isolated from natural products. The structural determination of these compounds is the job of the chemist. There are several instrumental techniques used to determine the structures of organic compounds. These include NMR, UV/visible, infrared spectroscopy, mass spectrometry, and X-ray crystallography. Of all the instrumental techniques listed, infrared spectroscopy and mass spectrometry are the two most popular techniques, mainly because they tend to be less expensive and give us the most structural information. This book is an introductory text designed to acquaint undergraduate and graduate students with the basic theory and interpretative techniques of mass spectrometry. Much of the material in this text has been used over a period of several years for teaching courses in materials characterization and chemical analysis. It presents the mass spectra of the major classes of organic compounds and correlates the fragmentation pattern of each spectrum with the structural features of the compound it represents. This has been done for hydrocarbons, organic acids, ketones, aldehydes, esters, anhydrides, phenols, amines, and amides. The text discusses the origin of the fragments, techniques, innovations, and applications in mass spectrometry. It is interspersed with many illustrations, examples, an adequate but not overwhelming bibliography, and problems for students. It will serve as a lecture text for a one-semester course in mass spectrometry or can be used to teach the mass spectra portion of a broader course in material characterization and chemical analysis.

Download or read book Natural Aphrodisiacs written by Ravi K. Puri Ph.D. and published by Xlibris Corporation. This book was released on 2011-12-05 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread use of effective prescription drugs for erectile dysfunction has helped advance societys acceptance of talking about sexual dysfunction for both men and women. As the authors elegantly describe, sexual dysfunction and attempts at treating it have been around for as long as sexuality itself. Its no surprise that history is full of myths about aphrodisiacs. Despite all the advances we have made in medicine, the myth of the aphrodisiacs is as powerful as ever. However, sexual dysfunction is very often a complex problem requiring careful, thoughtful and educated treatment. Rarely is there quick natural fix. Consumers need to do their homework before buying into the claims of companies selling natural aphrodisiacs. This book is an excellent resource for those seeking to educate themselves about the history, effectiveness, safety and future of natural aphrodisiacs. Nevertheless, the information contained within the text is also important and valuable for both sides of the patient-physician equation in the treatment of sexual dysfunction. Siobhan Hyland McGaughey, M.D. Urologist Urology Associates of central Missouri Columbia, MO 65201 The authors have expressed very clearly the various merits and demerits of natural aphrodisiac products on the market. Discussion on the future prospects of plant used as aphrodisiacs is excellent information for the phytochemists who are interested to pursue research limitations in the area of existing natural aphrodisiacs and their standardizations is consistent with the rising interest of global consumers in green environment. A special effort in creating the drawings of the natural products for enabling readers to identify the natural products is phenomenal. I recommend this book to the lovers of natural products without any hesitation. I hope that manufacturers, scholars and consumers of natural aphrodisiac products will take advantage of this document in years to come. Usha Chowdhary, Ph.D. Professor, Human Environmental Sciences Central Michigan University Mount Pleasant, MI 48859 The latest research on herbal aphrodisiacs cited by the authors is very impressive. The appropriate quotations at the beginning of each chapter are very fascinating. It is a comprehensive compendium on natural aphrodisiacs comprising their origin, myth, chemistry, pharmacology, risk and romance. Hand drawings of the plants are excellent and depict their morphological characteristics that can be helpful in identifying them. The book is actually a ready reckoner for physicians, pharmacist, or herbalists for guiding the patients who are incorporating natural products in their daily regime. K. C. Varma, Ph.D. Emeritus Professor & Chief Editor Indian Journal of Natural Products, India
