Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of its kind that focuses on the chemistry and biology of ellagitannins, a special class of naturally occurring polyphenols which have so far not received the attention they deserve. These polyphenolic substances are found in many plants, including numerous food sources. They not only exhibit unique structural features that fascinate most chemists who are aware of their existence, but also express remarkable biological activities that have yet to attract the interest of the pharmaceutical industry. This is surprising because ellagitannins have been identified as active principles in traditional Chinese medicines.

Available in PDF, EPUB and Kindle. Book excerpt: RECENT ADVANCES IN POLYPHENOL RESEARCH Plant polyphenols are secondary metabolites that constitute one of the most common and widespread groups of natural products. They are essential plant components for adaptation to the environment and possess a large and diverse range of biological functions that provide many benefits to both plants and humans. Polyphenols, from their structurally simplest forms to their oligo/polymeric versions (i.e. tannin and lignin), are phytoestrogens, plant pigments, antioxidants, and structural components of the plant cell wall. The interaction between tannins and proteins is involved in plant defense against predation, cause astringency in foods and beverages, and affect the nutritional and health properties of human and animal food plants. This seventh volume of the highly regarded Recent Advances in Polyphenol Research series is edited by Jess Dreher Reed, Victor Armando Pereira de Freitas, and Stéphane Quideau, and brings together chapters written by some of the leading experts working in the polyphenol sciences today. Topics covered include: Chemistry and physicochemistry Biosynthesis, genetics and metabolic engineering Roles in plants and ecosystems Food, nutrition and health Applied polyphenols Distilling the most recent and illuminating data available, this new volume is an invaluable resource for chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, biologists, ecologists, food scientists and nutritionists.
Download or read book Plant Polyphenols written by Richard W. Hemingway and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1027 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was developed from the proceedings of the 2nd North American Tan nin Conference held in Houghton, Michigan, June, 1991. The objective of this con ference was to bring together people with a common interest in plant polyphenols and to promote interdisciplinary interactions that will lead to a bet ter understand ing of the importance of these substances. Another objective of this conference was to extend the 'tannin family' by making special efforts to encourage participation by scientists outside the United States, obtain more coverage of the hydrolyzable tannins, and further broaden the scope of coverage from the initial concentration on forestry and forest products. Com parison of the contents of this book with 'Chemistry and Significance of Condensed Tannins' that resulted from the proceedings of the 1st North American Tannin Conference shows the degree that these objectives were met. In developing the second conference, care was taken to assure that this book extends rather than duplicates the coverage of the first conference. Therefore, the two books should be taken together to obtain an up to date coverage of the broad area of chemistry and significance of plant polyphenols. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We thank the Conference Assistance Staff of Michigan Technological University for their help in planning and conducting the conference.

Download or read book Handbook of Food Bioactive Ingredients written by Seid Mahdi Jafari and published by Springer Nature. This book was released on 2023-10-15 with total page 1576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioactive ingredients, including both bioactive compounds and bioactive live organisms, are present in small amounts in natural sources such as fruits and vegetables. These ingredients have been continuously investigated during the last few decades and the epidemiological data suggest that their intake is associated with significant decreased risk of various disorders and chronic diseases owing to their anti-oxidant, anti-bacterial and anti-inflammatory qualities. Some of these natural ingredients such as catechins, curcumin, resveratrol, oleuropein, quercetin, rutin, hesperidin, sulforaphane, ellagic acid, and anthocyanins, have been studied as factors with possible direct or indirect effect on specific molecular pathways which are playing vital roles in the association with the pathophysiology of the chronic diseases such as cancer. In light of this, natural foods and food-derived products rich in bioactives have received recent growing attention. It has been reported that frequent consumption of fruits, vegetables, and their associated natural products have many health-promoting benefits that protect against degenerative illnesses including heart disease, arthritis, cancer, immune system decline, brain dysfunction, inflammation and cataracts. Functional foods and medicinal supplements containing encapsulated bioactive materials will be the future of new emerging products in the food and pharma industries. Such products present therapeutical and medicinal properties that can prevent and/or cure specific chronic diseases and disorders. Handbook Of Bioactive Ingredients provides a systematic overview of different food bioactive ingredients describing their chemistry, structure, functionality, safety/toxicity, oral delivery and their applications in functional foods.

Download or read book Plant Phenolics in Abiotic Stress Management written by Rafiq Lone and published by Springer Nature. This book was released on 2023-01-13 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive collection of information on the role of plant phenolics in stress management in plants. The main focus of this book is to address the abiotic stress management in plants by plant phenolics under varied environments. Plant metabolic networks contribute significantly to the plasticity of plant metabolism, which is required to afford the sessile lifestyle of a land plant under changing environmental conditions. In natural systems, plants face a plethora of antagonists and thus possess a myriad of defenses and have evolved multiple defense mechanisms by which they can cope with various kinds of stresses for adaptation. Plant phenolics being ubiquitous have been extracted from every plant part such as roots, stem, leaves, flowers, fruits, and seeds and thus plays important role in adapting the plants to the varied environment. The book will provide readers with an up-to-date review of this dynamic field and sets the direction for future research. This book is of interest and use to a diverse range of topics of regulation of abiotic stress in plants. Bringing together work from leading international researchers, it is also a valuable reading material for plant and agricultural scientists, academics, researchers, students, and teachers wanting to gain insights into the role of plant phenolics in stress management in plants for sustainable agriculture.
