Download or read book Occurrence and Use of Hallucinogenic Mushrooms Containing Psilocybin Alkaloids written by Christer Andersson and published by Nordic Council of Ministers. This book was released on 2009 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: In some parts of the world mushrooms have had a central role in religious ritual ceremonies. Ethnomycological studies among the Indian tribes of Mexico - the Aztecs and the Chichimecas - revealed the mushrooms to be hallucinogenic. Chemists from a leading Pharmaceutical company took over, isolated and described the mushroom alkaloid psilocybin, that upon dephosphorylation after collection of the mushroom or in the human body, form psilocin that is the active hallucinogenic compound. For a long time psilocybin/psilocin was expected to become a constituent of psychedelic drugs useful for treatment of specific psychoses. As the effect of psilocybin/psilocin resembles that of LSD the isolated compound, as well as mushrooms containing the compound, became popular among recreational users of hallucinogenic drugs in Western America, and from there the habit of using these mushrooms have spread around the world. Psilocybin/psilocin is legally prohibited in many countries which usually treat the compound as a narcotic drug. Some countries also prohibit the use of some or all psilocybin-containing mushrooms. In this respect, the legal situation differs between Nordic countries. Although psilocybin-containing mushrooms are not what Nordic mushroom pickers are trying to find as food or food supplement, there is a risk, admittedly small, that these mushrooms accidentally will be collected. At the present situation, this may be a legal problem in some Nordic countries. This document aims at identifying when this might be the case without going into legal interpretations.

Download or read book Cucurbitacins in Plant Food written by Jørn Gry and published by Nordic Council of Ministers. This book was released on 2006 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poisoning due to Cucurbitaceous vegetables seems to be linked to intake of immensely bitter vegetables. The bitter and toxic compounds in these vegetables are cucurbitacins, which are well known in wild varieties of these food plants and their related species. The cultivated forms, on the other hand, have during cultivation been selected for being free of the bitter and toxic compounds. Occasionally, cultivars of cucurbitaceous food plants (e.g. squash) back-mutate and regain the ability to produce toxic amounts of cucurbitacins. This review summarises the information available on cucurbitacins in food plants of the family Cucurbitaceae, with the aim to lay down background information required to evaluate the potential risk of being intoxicated by cucurbitacins as a part of the safety assessment of cucurbitaceous food plants, and especially in relation to genetically modified Cucurbitaceous plants.

Download or read book Intake of caffeine and other methylxanthines during pregnancy and risk for adverse effects in pregnant women and their foetuses written by H. C. Andersson and published by Nordic Council of Ministers. This book was released on 2004 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part of the report deals with occurrence of methylxanthines in foods, beverages, and medicines, and estimates of caffeine intake. In addition, a short review of the pharmacological and toxicological actions of caffeine is given. The second and main part of the report reviews available information from epidemiological studies on the potential health hazards to the human foetus associated with parental intake during pregnancy of caffeine and related methylxanthines in foods, beverages and medicines. The studied adverse effects are influence on fertility, spontaneous abortion, congenital malformation, pre-term delivery, foetal growth retardation, foetal behaviour and effects on neonates, infants and young children. The conclusion of the report demonstrates the need for limiting caffeine exposure during pregnancy. The Nordic Working Group on Food Toxicology and Risk Evaluation (NNT) recognizes that the human exposure to caffeine and related compounds causes a spectrum of pharmacological effects, for instance cardiovascular, renal, neurological and behavioural effects. The increasing use of caffeine and related methylxanthines in various foods and beverages consumed by children and adolescents cause concern. NNT recommends that a full hazard characterization of caffeine and related methylxanthines should be performed with the aim to reach a conclusion about the upper safe level of intake of these compounds.

Download or read book Biodiversity written by Ewan J T Chrystal and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuing quest for new drugs and agrochemicals has seen researchers looking to the natural world for potential products. Plants and microorganisms have long been investigated as sources of new lead compounds, but the scope of this book has been widened to include substances derived from marine organisms. Advances in genetic engineering, high throughput screening and structure elucidation have also opened up further avenues for exploration. Competitive pressure from the field of combinatorial chemistry has expedited new approaches to natural product analysis and stimulated debate on the industrial utilization of natural products. Biodiversity: New Leads for the Pharmaceutical and Agrochemical Industries reviews and discusses aspects of modern natural products research. The central theme of many articles is the sustainable use of global biodiversity. Microbial, plant and marine products are presented as the sources of new drugs, including antifungal products, antibiotics, anticancer agents and animal health products. There is also coverage of the biosynthesis of polyketides and the chemical synthesis of natural products and their derivatives. A unique blend of industrial and academic perspectives on the importance of biodiversity and natural products, this book will prove an important source of state-of-the-art information for researchers, teachers and graduates in the chemical and biological sciences.

Download or read book Plant derived Natural Products written by Anne E. Osbourn and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants produce a huge array of natural products (secondary metabolites). These compounds have important ecological functions, providing protection against attack by herbivores and microbes and serving as attractants for pollinators and seed-dispersing agents. They may also contribute to competition and invasiveness by suppressing the growth of neighboring plant species (a phenomenon known as allelopathy). Humans exploit natural products as sources of drugs, flavoring agents, fragrances and for a wide range of other applications. Rapid progress has been made in recent years in understanding natural product synthesis, regulation and function and the evolution of metabolic diversity. It is timely to bring this information together with contemporary advances in chemistry, plant biology, ecology, agronomy and human health to provide a comprehensive guide to plant-derived natural products. Plant-derived natural products: synthesis, function and application provides an informative and accessible overview of the different facets of the field, ranging from an introduction to the different classes of natural products through developments in natural product chemistry and biology to ecological interactions and the significance of plant-derived natural products for humans. In the final section of the book a series of chapters on new trends covers metabolic engineering, genome-wide approaches, the metabolic consequences of genetic modification, developments in traditional medicines and nutraceuticals, natural products as leads for drug discovery and novel non-food crops.
