Download or read book Medicinal Plants written by Halina Maria Ekiert and published by Springer Nature. This book was released on 2021-09-01 with total page 900 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medicinal plant research is an evergreen subject. There is a tremendous increase in popularity of herbal medicine in traditional medicine, ethnomedicine, modern medicine and as over the counter food supplements. Even after this increased demand, supply is neither uniform nor assured as most of these plants are collected from wild. In developing countries of tropical and subtropical regions where majority of herbal drugs are produced, this is not organised sector making it vulnerable to several malpractices, hence standardization of all aspects required. This has also negative impact on biodiversity and conservation of plants as well as supply of uniform material. This book is aimed to provide up to date information about sustainable use of selected medicinal plants, their active ingredients and efforts made to domesticate them to ensured uniform supply. Development of agrotechnology, biotechnology and cultivation practices using conventional and non-conventional methods are presented. Where these efforts will lead the medicinal plant research and future perspective are discussed. The chapters are written by well recognised group leaders in working in the field. The book contains topics on general biology of medicinal plants, their sustainable use and, cultivation and domestication efforts. A uniform chapter structure has been designed to keep consistency. The book will be useful for academicians, agriculturists, biotechnologists and researcher, and industries involved in manufacturing herbal drugs and supplementary products.

Download or read book Nutritional Composition of Fruit Cultivars written by Monique Simmonds and published by Academic Press. This book was released on 2015-10-16 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutritional Composition of Fruit Cultivars provides readers with the latest information on the health related properties of foods, making the documentation of the nutritive value of historical cultivars especially urgent, especially before they are lost and can't be effectively compared to modern cultivars. Because there is considerable diversity and a substantial body of the compositional studies directed towards commercial varieties, this information is useful for identifying traits and features that may be transposed from one variety to another. In addition, compositional and sensory features may also be used for commercialization and to characterize adulteration. Detailed characterization of cultivars can be used to identify "super-foods". Alternatively, unmasked historical cultivars may be the focus of reinvigorated commercial practices. Each chapter in this book has sections on the botanical aspects, the composition of traditional or ancient cultivars, the composition of modern cultivars, a focus on areas of research, the specialty of the communicating author of each chapter, and summary points. - Presents the botanical aspects and composition of both traditional and modern plants, including in-depth insight into current research, and overall summary points for each fruit for consistent comparison and ease of reference - Provides important information in the consideration of preservation, transference, or re-introduction of historical/traditional cultivars into current crop science - Provides details on compositional and sensory parameters, from aroma and taste to micro- and macronutrients - Includes data on nutraceuticals and novel components that have proven to impact on, or be important in, food quality, storage, processing, storage, and marketing
Download or read book Birch Reduction of Aromatic Compounds written by A. A. Akhrem and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birch reduction (see reviews [1-5]) is the name given to the reaction of unsaturated organic compounds with alkali metals and alcohols in liquid am monia. This method was first used for aromatic compounds in 1937 by Wooster [6J, who showed that benzene and its derivatives are reduced by sodium in liq uid ammonia in the presence of an alcohol, while this reaction does not take place in the absence of an alcohol. However, the general recognition and broad application of this reaction was achieved only after a series of investigations by Birch published from 1944 onwards [7J. Since the presence of an alcohol in the reaction medium is not indispen sable for pOlycyclic aromatic systems, the present review includes only deriv atives of the simplest aromatic compounds - benzene and naphthalene. 1 Reaction Mechanism The most probable mechanism of Birch reduction, adopted by the major ity of workers in this field [4, 8 -12] can be represented by the following stages: 'v\ I NH -'" ,. - i T 1 3 +--"'( a) , , ,e (NHa) NH 3) + ROH ----+ () ll. .

Download or read book The Conservation of Orbital Symmetry written by R. B. Woodward and published by Elsevier. This book was released on 2013-10-22 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Conservation of Orbital Symmetry examines the principle of conservation of orbital symmetry and its use. The central content of the principle was that reactions occur readily when there is congruence between orbital symmetry characteristics of reactants and products, and only with difficulty when that congruence does not obtain—or to put it more succinctly, orbital symmetry is conserved in concerted reaction. This principle is expected to endure, whatever the language in which it may be couched, or whatever greater precision may be developed in its application and extension. The book opens with a review of the elementary aspects of the molecular orbital theory of bonding. This is followed by separate chapters on correlation diagrams, the conservation of orbital symmetry, theory of electrocyclic reactions, theory of cycloadditions and cycloreversions, and theory of sigmatropic reactions. Subsequent chapters deal with group transfers and eliminations; secondary conformational effects in concerted cycloaddition reactions; and generalized selection rules for pericyclic reactions.

Available in PDF, EPUB and Kindle. Book excerpt: The first authoritative book on using silver cations in organic chemistry—for catalysis and more! With more sophisticated catalytic methodologies fueling a resurgence in the study of cation-based chemistry, gold and platinum have stepped to the fore as the unique agents used to create new chemical reactions. Although these metals have become a primary focus of researchers in the field, another coinage metal that is often overlooked—but is as powerful as the others—is silver, a far less costly alternative to gold and platinum in aiding the development of new reactions. Making a strong case for the use of silver as a catalyst and structural element in organometal constructs, this authoritative book is the first to explore the benefits of using silver in organic chemistry by taking a close look at silver’s unique reactivity and structural characteristics for the development of new methods and materials. Silver in Organic Chemistry is: The first book to address catalysis using silver, whose use in organic chemistry is on the verge of exploding A resource for researchers wishing to do chemistry with silver cations, an area that stands in the shadow of gold chemistry, but still glistens, demonstrating that all that glitters is not gold—sometimes it’s silver! A guide for “first attempts” in working with silver cations Edited by a very well-respected, highly visible authority in this field Silver in Organic Chemistry promotes further scientific discussion by offering important new ways to examine the future possibilities of an emerging field. By elevating the importance of silver chemistry, this thought-provoking guide illustrates how this versatile metal can become an increasingly significant player in opening the door to new catalytic organic reactions and new organometal materials.
Download or read book Wood Modification Technologies written by Dick Sandberg and published by CRC Press. This book was released on 2021-07-15 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The market for durable products using modified wood has increased substantially during the last few years. This is partly because of the restriction on the use of toxic preservatives due to environmental concerns, and to lower maintenance cost and time. Furthermore, as sustainability becomes a greater concern, the environmental impact of construction and interior materials is factored in planning by considering the whole life cycle and embodied energy of the materials used. Wood is modified to improve its intrinsic properties, enhance the range of applications of timber, and to acquire the form and functionality desired by engineers without calling the environmental friendliness into question. Wood modification processes are at various stages of development, and the challenges faced in scaling up to industrial applications differ. The aim of this book is to put together the key elements of the changes of wood constituents and the related changes in wood properties of modified wood. Further, a selection of the principal technologies implemented in wood modification are presented. This work is intended for researchers, professionals of timber construction, as well as students studying the science of materials, civil engineering and architecture. This work is not exhaustive, but intends to deliver an outline of the scientific disciplines necessary to apprehend the technologies of wood modification and its behavior during treatment, as well as during its use.
