Описание: The ground-state of molecular oxygen, O, is essential to many 2 indispensible metabolic processes of all aerobic life forms ranging from prokaryotes, protists, plants, and fungi to animals. Research by mammalian toxicologists and clinicians has unravelled persua- sive evidence that O dependence imposes universal toxicity to all 2 aerobic life processes. The basis of this paradox is that one-electron reduction of O2 generates the superoxide anion free radical, 0;-, from numerous biological sources; for example, redox-active autoxidizable molecules such as catecholamines, oxidoreductases, and subcellular organelles such as mitochondria, endoplasmic reti'C- ulum (microsomes), nuclei, and chloroplasts. Oxygen is also acti- vated in biologically relevant photosensitizing reactions to highly re- active singlet oxygen, 10, 2 In all biological systems, 0;- undergoes further reduction to H 0 2 2 via Fenton reaction to the hydroxyl radical, -OH. These, and some other forms of activated O, constitute reactive oxygen species (ROS) 2 and/or metabolites (ROM). Both 'OH and 10 are the most reactive 2 forms of ROS known and among their deleterious reactions are ox- idation of proteins, DNA, steroidal compounds, and peroxidation of the cell membrane's unsaturated lipids to form unstable hydro- peroxides. Their many breakdown products include malondialde- hyde and hydroxynonenals that are themselves highly reactive and threaten cellular integrity and function. More importantly, they de- compose to free radicals that can continue to propagate the vicious lipid peroxidation chain reaction. This is the so-called endogenous oxidative stress with which all aerobic organisms must cope.

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.
