Available in PDF, EPUB and Kindle. Book excerpt: A Life to Remember This amazingly detailed memoir spans three continents and nearly a century of the life of Balawant Joshi. In it he recalls a journey beginning in a small village in southern India and ending in the southern United States. The son of a poor but brilliant school teacher and linguist, Joshi relates his beginnings at school, moving through hard-fought successes to the completion of the highest levels of education at Cambridge. Throughout the journey and for all his life, a philosophy of peace, regard for his fellow man, and an attitude of determination regardless of the pitfalls of life shine through his modest writing. Joshi expands on his long career in experimenting with plants and Natural Products for synthesis and use in pharmaceuticals in India, Switzerland, and the United States. He writes of family, weddings, and celebrations in India, and travels to many countries. He recalls a small but dangerous role he played in the fight for independence of India from Great Britain. Retired many years ago and living in Georgia, he loses his beloved wife, finds productive activity in a Natural Products, learns painting, and finds new friends and companionship throughout his senior years. Joshi is a great example for all of a life well lived and a love for humanity and a mind still keen and full of stories at the age of ninety.

Book excerpt: The cyanogenic glycosides, here defined as glycosidic derivatives of iX-hydroxynitriles, represent a rather limited class of natural products, which are widely distributed in the plant kingdom and, to a small ex tent, even in animals. A characteristic feature of these glycosides is their ability to release hydrocyanic acid on treatment with dilute acids or appropriate enzymes. The term "cyanogenic" is used to designate this property, regardless of whether pure substances, plants, or animals, are serving as the source. In the latter cases the term "cyanophoric" is occasionally employed synonymously. Cyanogenesis in plants was probably first discovered by SCHRADER in 1803 (Io3) working with bitter almonds. In 1830, ROBIQUET and BOUTRON-CHARLARD (IOO) succeeded in isolating the parent glycoside, namely amygdalin. Over the years, a total of 18 cyanogenic glycosides have been isolated and characterized more or less completely (Table I, p. 76). It will be noted that the majority of these compounds has been isolated in the era of classical organic chemistry and that progress in .discovering new compounds, not to mention new structural types, has been surprisingly slow. It is worth remembering here that the mechanism ·of cyanogenesis has been established only in the minority of known cyanogenic species. The cyanogenic glycosides have last been reviewed in 1958 by DILLE MANN (36). Since then, no complete reviews in this field have appeared. It is the purpose of the present article to survey the more recent ad vances and, hopefully, to stimulate continued interest in these interesting .compounds.

Download or read book Colorants for Non Textile Applications written by H.S. Freeman and published by Elsevier. This book was released on 2000-05-03 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the chemistry of natural and synthetic dyes produced for non-textile markets, where much new basic research in color chemistry is now taking place.The first group of chapters covers the design, synthesis, properties and application technology pertaining to dyes for digital printing and photography. The reader will be pleased with the breadth and depth of information presented in each case. Of particular interest is the discussion of strategies for the design of dyes in these categories, with emphasis on enhancing technical properties. In view of certain new developments, the ink-jet chapter includes results from studies pertaining to dyes for textiles.The three chapters comprising Section II of this volume cover the broad subject of dyes for food, drug and cosmetic applications and then provide an in-depth look at dyes for biomedical applications and molecular recognition. The chapter on dyes for molecular recognition places emphasis on applications in the biological sciences, including sensory materials and artificial receptors. While the former two topics have been covered elsewhere in the past, the present chapters are unequalled in scope.Section III provides an in-depth review of the design of laser dyes and dye-based functional materials. In the first of the two chapters, the major principles of laser operation are summarized. This is followed by a discussion of spectroscopic properties, such as activation and deactivation of absorbed light by laser dyes. Approaches to the development of new laser dyes are presented. The second chapter pertains to the synthesis of dicyanopyrazine-based multifunctional dyes. The visible and fluorescence spectra of these dyes in solution and the solid state are correlated with their three-dimensional molecular structures. Molecular stacking behavior and solid state properties of these "multifunctional" dye materials are presented.The final group of chapters pertains to natural dyes and dyes for natural substrates. In recent years, the impression among certain consumers that "natural" is better/safer has generated much interest in the use of natural dyes rather than synthetics. This has led to a few short discussion papers in which the environmental advantages to using natural dyes have been questioned. The initial chapter in this group provides both a historical look at natural dyes and a comprehensive compilation of natural dye structures and their sources. Though natural dyes are of interest as colorants for textiles, selected ones are used primarily in food and cosmetics.Chapter ten provides an update on the author's previous reviews of structure-color-relationships among precursors employed in the coloration of hair. Chemical constitutions characterizing hair dye structures are presented, along with a summary of available precursors and their environmental properties. Similarly, the chapter on leather dyes covers constitutions and nomenclature, in addition to providing interesting perspectives on the origin and use of leather, the dyeing of leather, and key environmental issues.This volume is concluded with another look at colors in nature. In this case, rather than revisiting colors in plant life, an interesting chapter dealing with color in the absence of colorants is presented. Chapter twelve covers basic concepts of color science and illustrates how 3-D assemblies leading to a plethora of colors are handled in nature. It is our hope that this atypical "color chemistry" chapter will invoke ideas that lead to the design of useful colorants.The chapters presented in this volume demonstrate that color chemistry still has much to offer individuals with inquiring minds who are searching for a career path. This work highlights the creativity of today's color chemists and the wide variety of interesting non-textile areas from which a career can be launched.

Download or read book Marine Natural Products V3 written by Poul Schever and published by Elsevier. This book was released on 2012-12-02 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Natural Products: Chemical and Biological Perspectives, Volume III, reviews the state of knowledge in the chemistry and biology of marine natural products. It attempts to bring together timely and critical reviews that are representative of major current researches and that, hopefully, will also foreshadow future trends. The volume's first chapter discusses separation techniques, including liquid-liquid extraction, membrane separation, chromatography, capillary gas chromatography, and high-performance liquid chromatography. This is followed by a chapter on amino acids that have been isolated from marine algae. Kainic acid, for instance, is a well-established ascaricide that was isolated from a red alga that had been known as an anthelmintic for a thousand years. Only recently, however, has it been recognized as a valuable tool in neurophy sinology. Subsequent chapters deal with nitrogenous pigments in marine invertebrates; and the phenomenon of bioluminescence, which is relatively rare among terrestrial organisms, but which is widespread among marine biota.
