This book provides an overview of antioxidants and antioxidant enzymes and their role in the mechanisms of signaling and cellular tolerance under stress in plant systems.
Major reactive oxygen species (ROS)-scavenging/modulating enzymes include the superoxide dismutase (SOD) that dismutates O2 into H2O2, which is followed by the coordinated action of a set of enzymes including catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxiredoxins (Prx) that remove H2O2. In addition to the ROS scavenging enzymes, a number of other enzymes are found in various subcellular compartments, which are involved in maintaining such redox homeostasis either by directly scavenging particular ROS and ROS-byproducts or by replenishing antioxidants. In that respect, these enzymes can be also considered antioxidants. Such enzymes include monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), glutathione reductase (GR), alternative oxidases (AOXs), peroxidases (PODs) and glutathione S-transferases (GSTs). Some non-enzymatic antioxidants, such as ascorbic acid (vitamin C), carotenes (provitamin A), tocopherols (vitamin E), and glutathione (GSH), work in concert with antioxidant enzymes to sustain an intracellular steady-state level of ROS that promotes plant growth, development, cell cycles and hormone signaling, and reinforces the responses to abiotic and biotic environmental stressors.
Offering a unique compilation of information on antioxidants and antioxidant enzymes, this is a valuable resource for advanced students and researchers working on plant biochemistry, physiology, biotechnology, and signaling in cell organelles, and those specializing in plant enzyme technology.

Описание: Procyanidins are phenolic compounds from plants and they are abundant in our diet. Research studies on procyanidins have shown that they have many health benefits, especially as preventive agents for cancer, cardiovascular diseases and diabetes. High concentrations of procyanidins can be found in plants and foods such as red wine, grapes, grape seeds, cocoa, berries and apples. The first chapter of this book reviews the occurrence and the structure of these compounds. Since the extraction method is considered a critical step in procyanidin analysis, the second chapter describes the various methods used in literature so far with reference to the most important factors influencing the extraction. Furthermore, common separation and detection methods like high performance liquid chromatography and mass spectrometry are presented in order to give the complex image of the existing methods described so far. These principles of procyanidin fingerprinting are reflected further in studying the seed shells of the Japanese horse chestnut (Aesculus turbinata BLUME), discarded as waste materials after the preparation of edible seeds. The highly polymeric proanthocyanidins from the Japanese horse chestnut were tested for their health benefits, and this is presented in Chapter Three. As the interest in antioxidant compounds increases, the interest in studying their bioavailability has increased as well. In the context of controversy surrounding the studies on procyandins absorption and metabolisation, the next chapter tries to present different points of view related to this matter. Several applications of procyanidins in food systems are reviewed in Chapter Five, including: Co-encapsulation of green tea catechins on probiotic bacteria viability during simulated gastrointestinal digestion, stability of polyphenolic compounds on alginate, and chitosan microcapsules and procyanidin effectiveness after incorporation into food edible films. The final part of this book investigates the procyanidin structure-activity relationship and mechanisms of cardiovascular diseases because the intake of procyanidins has been associated with reduced cardiovascular disease risk by epidemiologic studies. The expertise of the authors contributing to this book is useful for graduates studying food science and technology, nutrition, pharmacy and health, and for researchers, scientists, policymakers and professionals from food, pharmacy, nutrition and biotechnology industries working on procyanidins characterization, antioxidant properties and health benefits.

Описание: The scientific world and modern society today is experiencing the dawning of an era of herbal medicine. Extensive research has shown that aromatic plants are important anti-inflammatory, antioxidant, anti aging and immune boosting delectable foods, with the magic and miracle to boost our immune system providing us with extended and an improved quality of life. Apart from making bland recipes into welcoming or interesting victories, herbs and spices have stirred the minds of the research community to look deeper into its active components from a functional perspective. It is essential to present the scientific and medicinal aspect of herbs and spices together with the analysis of constituents, its medicinal application, toxicology and its physiological effects. Herbs and spices with high levels of antioxidants are in great demand as they tend to promote health and prevent diseases naturally assuring increased safety and reliability for consumers. Herbs and spices are not only known for taste and flavor, but today research has opened up a new realm in which the antioxidant properties of these aromatic plants provide preservation for foods and health benefits for consumers who look forward to concrete scientific research to guide them further and explore herbal medicine. The aim of this book is to create awareness in society about the reliability of medicinal properties of certain herbs and spices through scientific and scholarly research.
