This book offers a comprehensive perspective of herbal medicine phytochemistry and explores the application of plant extracts as bioactive compounds in disease prevention and treatment in modern or traditional medicine. The book starts with an introduction to the history and value of herbal medicine, followed by 3 parts covering the main phytochemical components and metabolites in herbal medicine, different uses and practices in herbal medicine, including a region-wise analysis of methods and practices and an overview of regulations and policies for herbal medicinal practitioners, and the advances and challenges in quality assessment of herbal medicine. Plants generally have the tendency to bioaccumulate trace metals from the environment and they are easily contaminated by microorganisms from water sources and poor hygiene practices of the herbalist. Quality assessment and assurance is, thus, a pertinent challenge in herbal medicine practice (i.e., in remedy formulation and application), and this book offers an authoritative perspective on this topic, covering aspects such as quality control strategies, preparation techniques, chemical quantification in phytomedicine, and the efficacy and safety of herbal remedies. Moreover, in this book, readers will find valuable insights into the latest trends and developments in the field, and a critical review of the application of medicinal plants to treat cardiovascular, digestive, respiratory neurological and reproductive diseases. Particular attention is given to the advances and trends in the field, and readers will learn about the latest biotechnological approaches, the use of nanotechnology in herbal medicine, metabolomic analysis of medicinal plants, big data application in herbal medicine, and the value of herbal medicine towards sustainability. Given its breadth, this book is aimed at researchers, academics, practitioners and professionals working in the fields of natural, life, health, clinical, and biomedical sciences, and interested in herbal remedies, pharmacology, pharmacognosy, human nutrition and dietetics, plant biology, and biotechnology/microbiology.

This book provides the reader with the latest research on vibrational circular dichroism (VCD) spectroscopy including its useful features and applications to many fields. The book starts from an unresolved question in gel chemistry of how component molecules are organized in the flexible fibrils of gels. VCD spectroscopy was successful in giving a clear answer to this mystery. The book also describes a key aspect of this technique lay in the fact that VCD signals were remarkably enhanced when chiral molecules formed a stereoregular molecular array over a few hundred nanometers. VCD spectroscopy was also applied to other topics involving chiral molecules such as the chiral discrimination mechanism in heterogeneous asymmetric catalysis and the build-up of supramolecular chirality in molecular crystals. Furthermore, the book covers the recent instrument developments leading to multi-dimensional VCD measurements with the coordinates of wavenumber, space and time. This progress has opened up new biological and medical applications such as the heterogenous distributions of protein domains in insect wings and the quality control of chiral drugs. The last part of the book presents the possibility of medical diagnosis of Alzheimer's disease through multi-dimensional VCD analyses. This book appeals not only to researchers and students who study spectroscopy but also to ones in catalysis, biology and medicine as users of the VCD methods.

In the fields of biologically active materials and functional materials, fluorinated organic materials are becoming a focus of significant interest. Over the past decade synthetic methodologies and reagents in fluorine chemistry have been developed, especially stereocontrolled synthetic methods, enzymatic resolution to synthesize enantiomers, fluoromethylated reagents, and fluorination reagents. These methods have contributed to the opening of new pathways for fluorinated materials. However, few fluorinated materials have been put to commercial use. Furthermore, there remain problems to be solved, such as the handling of the materials, availability of reagents and selectivity (stereo-, regio-, and/or chemoselectivity). Research chemists, technical engineers, and graduate students in all branches of chemistry, pharmaceutics, and material science interested in fluorinated materials need to know detailed experimental procedures of how to synthesize the target fluorinated materials. This volume summarizes the chemical and microbial methods for obtaining functionalized fluorinated materials for use as building blocks; detailed experimental methods (reaction conditions, solvent, temperature, handling techniques, etc.); and the stereoview (possible absolute configuration) of the structures with spectral data. Mono-, di-, tri-, and polyfluorinated materials derived from fluorinating agents, fluoromethylated reagents and building blocks are summarized. A chemical name index, molecular formula index, and reagent index are also included.

This volume describes the recent developments in the free-radical mediated synthesis and elaboration of heterocycles. The first chapter, dealing with radical cascade processes illustrates the power and the beauty of radical chemistry with some striking examples of total synthesis of complex natural heterocycles. As organic chemists strive towards sustainability, radical chemistry has recently seen major advances and efforts in this direction, including C-H activation of arenes and unactivated alkyl groups. Photochemical activation, for a long time the preferred mode of activation in radical chemistry has also seen an unexpected revival with the advent of visible light metal- and organocatalyzed photoredox processes. A survey of these emerging areas is provided along with the concepts at the origin of these developments. The venerable Minisci reaction allows for direct access to functionalized heterocycles. This process has lately seen an interesting renaissance and is discussed in this volume. Addition of heteroatom-centered radicals onto unsaturated systems constitutes another powerful method to construct heterocycles. Examples of such a strategy are proposed along with the formation of various heterocycles relying on homolytic substitution at sulfur, phosphorus and selenium. Additionally free-radical functionalization of reactive functional groups including isonitriles, isothiocyanates and related unsaturated systems which offer a straightforward route towards useful aromatic and non-aromatic heterocycles are discussed. Finally, as metals are able to trigger single electron transfer both in reductive and oxidative modes this provides another possibility for the synthesis of heterocycles. Significant research efforts have focused on the use of samarium, copper and other metals to access a broad variety of heterocycles in a single pot process, starting from readily available raw material. Examples and mechanistic insights are discussed by experts in thisarea.
