Download or read book Antioxidant and Anti-aging Action of Plant Polyphenols written by Christophe Hano. This book was released on 2020-11-13. Available in PDF, EPUB and Kindle. Book excerpt: Polyphenols are plant non-nutrient natural products, or plant secondary metabolites, found in fruits, vegetables and seeds that we consume daily. Their intakes from fruit, vegetables, seeds, and nuts are associated with lower risks of chronic and age-related degenerative diseases. Aging is a dynamic and complex biological process involving multiple actors and subject to a number of genetic and/or environmental influences. The famous free radical theory of aging proposed by Prof. Harman in 1956 states that free radicals lead to oxidative damage, causing cellular dysfunction and physiological decline, and are responsible for aging, with the appearance of degenerative diseases and eventually death. From this hypothesis, antioxidant molecules are capable of slowing down the aging process through the successful scavenging of radical oxygen and nitrogen species. Polyphenols have been shown to prolong the lifespan of different model species operating through a well-conserved antioxidant mechanism. This collection of research and review articles covers the most recent advances in the use of plant polyphenols, ranging from their biological properties and possible functions as medicines, the importance of traditional medicines as a source of inspiration, the rationalization of new uses of plant extracts which lead to applications in modern medicine, the status of modern green-chemistry extraction methods, to some reflections on future prospects.

Book Synopsis Recent Advances in Polyphenol Research, Volume 2 by : Celestino Santos-Buelga

Download or read book Recent Advances in Polyphenol Research, Volume 2 written by Celestino Santos-Buelga. This book was released on 2011-01-04. Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Polyphenol Research Volume 2 Edited by Santos-Buelga, Escribano-Bailon and Lattanzio Plant phenolics are secondary metabolites that constitute one of the most common and widespread groups of substances in plants. Polyphenols have a large and diverse array of beneficial effects on both plants and animals. For example they are famous as antioxidants, hormones, constituents of essential oils and natural neurotransmitters. Sponsored by Groupe Polyphenols, this publication, which is the second volume in this ground-breaking series, is edited by Celestino Santos-Buelga, Maria Teresa Escribano-Bailon, and Vincenzo Lattanzio, who have drawn together an impressive list of internationally respected authors, each providing cutting edge chapters covering some of the major topics of recent research and interest. Information included in this important new addition to the series include the following areas: • Flavonoid chemistry of the leguminosae • Chemistry and biological activity of ellagitannins • Chemistry and function of anthocyanins in plants • An update of chemical pathways leading to new phenolic pigments during wine ageing • Metabolic engineering of the flavonoid pathway • The translation of chemical properties of polyphenols into biological activity with impacts in human health • Plant phenolic compounds controlling leaf movement • Biological activity of phenolics in plants Chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, food scientists and nutritionists will all find this book an invaluable resource. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves.

Download or read book Antioxidant Activity of Polyphenolic Plant Extracts written by Dimitrios Stagos. This book was released on 2021-03-19. Available in PDF, EPUB and Kindle. Book excerpt: “Antioxidant Activity of Polyphenolic Plant Extracts” is a collection of scientific articles regarding polyphenols, that is, substances occurring naturally in plants and exhibiting many beneficial effects on human health. Among polyphenols’ interesting biological properties, their antioxidant activity is considered the most important. This book brings together experts from different research fields on topics related to polyphenols, such as their isolation and purification, assessment of their antioxidant activity, prevention from oxidative stress-induced diseases and use as food additives. The polyphenols used in the present studies are derived from a great variety of plants, ranging from well-known species to rare ones that are only found in specific regions. Moreover, some of the studies provide evidence that polyphenols may be used for the prevention and treatment of common diseases such as diabetes mellitus, Alzheimers’ disease, cardiovascular and intestinal diseases. Importantly, in several of the studies “green extraction methods” for the isolation of polyphenols were developed using modern technologies, where few or no organic solvents were used, in order to minimize environmental and health impacts.
