Download or read book Recent Developments in the Chemistry of Natural Phenolic Compounds written by W. D. Ollis and published by Elsevier. This book was released on 2013-10-22 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Development in the Chemistry of Natural Phenolic Compounds covers the proceedings of the Third Plant Phenolics Group Symposium, held in April 1960. This symposium brings together important and interesting developments in the chemistry of naturally occurring phenolic compounds. This book is divided into 12 chapters that specifically concern with the biosynthesis and the determination of the structure of phenolic natural products. The first three chapters discuss the various aspects of biosynthesis and the structural and biogenetic relationships among a large number of natural products. These chapters also consider the biosynthesis of flavonoids, with particular reference to the isoflavones. The succeeding chapter highlights the variety of structures shown by phenolic compounds containing terpenoid substituents. Another chapter deals with the recent syntheses of various natural products by methods involving oxidative coupling of phenolic precursors. Other chapters are devoted to the relationship of phenolic precursors to natural biosynthetical routes. The rest of the book deals with structural investigations, which have led to the recognition of several classes of natural products. This book is of great value to organic chemists and researchers.

Bioactive compounds have been identified from diverse sources and their therapeutic benefits, nutritional value and protective effects in human and animal healthcare have underpinned their application as pharmaceuticals and functional food ingredients. The orderly study of biologically active products and the exploration of potential biological activities of these secondary metabolites, including their clinical applications, standardization, quality control, mode of action and potential biomolecular interactions, has emerged as one of the most exciting developments in modern natural medicine. Biotechnology of Bioactive Compounds describes the current stage of knowledge on the production of bioactive compounds from microbial, algal and vegetable sources. In addition, the molecular approach for screening bioactive compounds is also discussed, as well as examples of applications of these compounds on human health. The first half of the book comprises information on diverse sources of bioactive compounds, ranging from microorganisms and algae to plants and dietary foods. The second half of the book reviews synthetic approaches, as well as selected bioactivities and biotechnological and biomedical potential. The bioactive compounds profiled include compounds such as C-phycocyanins, glycosides, phytosterols and natural steroids. An overview of the usage of bioactive compounds as antioxidants and anti-inflammatory agents, anti-allergic compounds and in stem cell research is also presented, along with an overview of the medicinal applications of plant-derived compounds. Biotechnology of Bioactive Compounds will be an informative text for undergraduate and graduate students of bio-medicinal chemistry who are keen to explore the potential of bioactive natural products. It also provides useful information for scientists working in various research fields where natural products have a primary role.

Download or read book Legacy Pathogenic and Emerging Contaminants in the Environment written by Manish Kumar and published by CRC Press. This book was released on 2021-12-31 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the time when legacy, pathogenic, and emerging contaminants must be talked about, understood, and dealt with together. While the geogenic contamination of the groundwater is a well-established phenomenon that is considered as legacy contaminants that risk people’s health globally, both pathogenic and emerging contaminants like various water-borne pathogens and pharmaceutical personal care products (PPCPs) are becoming imperative for their acute and chronic toxic effects. While contaminated groundwater consumption leads to skin pigmentation, hyperkeratosis, kidney damage, cardiovascular disease, and children’s overall development, poor sanitation-related pathogenic microorganisms cause a significant number of child and prenatal deaths. Simultaneously, antibiotic microbial resistance (AMR) is expected to kill 100 million people by 2050. However, there are rare texts that combine aspects of all these three under a single book cover. This book gives an understanding of the occurrence, fate, and transport of geogenic, microbial, and anthropogenic contaminants in the groundwater. It covers not only the scientific and technical aspects but also environmental, legal, and policy aspects for contaminant management in the environment under the paradigm shift of COVID-19. This book is intended to bring the focus on the natural contaminants—biotic or abiotic—in the post-COVID Anthropocene, which is illustrating a significant alteration of systems and the subsequent downstream impacts owing to globalization. This book has compiled global work on emergence, mass flow, partitioning, and activation of geogenic, emerging, and pathogenic contaminants in various spheres of environment with special emphasis on soil, sediment, and aquatic systems for enhancing the understanding on their migration and evolution for the welfare of mankind.
Download or read book Biodegradation of Selected Phenolic Compounds in a Simulated Sandy Surficial Florida Aquifer written by Chen Hsin Lin and published by . This book was released on 1988 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenolic compounds are commonly found contaminants in groundwater systems. In this research the sorption and biodegradation of phenol, 2, 4-d ichlorophenol (2,4-DCP) and pentachlorophenol (PCP) were investigated. The soil materials used were characterized as fine grained sands with negligible organic carbon contents. Freundlich sorption coefficients of 0.0158 for phenol and 0.0547 for 2,4-DCP were found. Pentachlorophenol was more strongly adsorbed with an adsorption coefficient of 1.12. In multi-compound systems competitive sorption was evident, and adsorption capacities were reduced by a margin ranging from 70% for phenol to 30% for both DCP and PCP. All three compounds exhibited nonlinear sorption behavior with a range of exponent values from 0.56 to 0.7. Desorption coefficients showed little difference from adsorption for phenol and 2,4-DCP, but were significantly different for PCP, indicating hysteresis of PCP sorptions. The retardation factors were 1.03 for phenol, 1.16 for 2,4- DCP and 2.26 for PCP. In batch biodegradation studies using indigenous soil bacteria phenol degraded quickly (t., _ = 12 hours) and was completely destroyed within three days. 2,4-DCP was also completely degraded but had taken 23 days (t, /_ = 7 days) . PCP was resistant to biodegradation with an average halflife of 120 days. In multi-compound systems, phenol degradation rates dropped off to 0.4 day (t, = 1.7 days) but PCP degradation rates increased to 0.008 day (t . = 86 days) . Biodegradation rates in column studies were obviously greater than in batch experiments, with the rate increase for PCP degradation being especially noticeable (t, = 12 days), because of larger bacterial populations and the dynamic flow conditions made the substrates more available to the bacteria. When controlled under an aerobic environment by the addition of hydrogen peroxide, all three phenolic compounds degraded fastest. under anoxic conditions both the microbial population buildup and the rate of phenolic compound degradation were slower but not by a wide margin. Bacterial growth in the columns did not reduce the hydraulic conductivity of the system, indicating the feasibility of applying in-situ biodegradation techniques to groundwater contamination problems.
