Synthesizing research from a wide variety of sources, this work offers a convenient guide to a clean, safe, inexpensive, non-toxic, non-polluting solvent that performs better than most conventional solvents. Natural Extracts Using Supercritical Carbon Dioxide reviews recent development in the technology and its applications to the food, flavor, fragrance, and pharmaceutical industries. It outlines the many advantages the method has over traditional methods like steam distillation, solvent extraction, and molecular distillation and it supports the popular trend toward the use of natural products in these industries.

Essentials of Botanical Extraction: Principles and Applications provides a unique, single source of valuable information on the various botanical extraction methods available, from conventional to the use of green and modern extraction technologies including ultrasounds, microwaves, pressurized liquids, and supercritical fluids. Most extracts obtained from botanicals are often poorly characterized with unidentified active or inactive constituents. A wise selection of an extraction strategy is vital to drug discovery from medicinal plants as extraction forms the basic first step in medicinal plant research. This book also explores the mathematical hypotheses and innovations in botanical extractions and analyzes different post extraction operations so that dependency on serendipity is reduced and the same be converted into programmed drug discovery. Reviews the history and current state of natural product drug discovery and development, highlighting successes and current issues Explains the application of chemometric tools in extraction process design and method development Introduces process intensification as applied to the processing of medicinal plant extracts for rapid and cost-effective extraction

Polyphenols in Plants assists plant scientists and dietary supplement producers in assessing polyphenol content and factors affecting their composition. It also aids in selecting sources and regulating environmental conditions affecting yield for more consistent and function dietary supplements. Polyphenols play key roles in the growth, regulation and structure of plants and vary widely within different plants. Stress, growth conditions and plant species modify polyphenol structure and content. This book describes techniques to identify, isolate and characterize polyphenols, taking mammalian toxicology into account as well. Defines conditions of growth affecting the polyphenol levels Describes assay and instrumentation techniques critical to identifying and defining polyphenols, critical to researchers and business development Documents how some polyphenols are dangerous to consume, important to dietary supplement industry, government regulators and lay public users

An Interpretation of "The Spirit of the Laws"
Author: Vickie B. Sullivan
Publisher: University of Chicago Press
Montesquieu is famous as a tireless critic of despotism, which he associates overtly with Asia and the Middle East and not with the apparently more moderate Western models of governance found throughout Europe. However, Vickie B. Sullivan argues that a creaful reading of Montesquieu's enormously influential The Spirit of the Law reveals the surprising result that he recognizes that Europe itself is susceptible to despotic practices - and that the threat emanates not from the East but rather from certain despotic ideas that inform Western institutions and practices. Sullivan guides readers through Montesquieu's sometimes veiled yet sharply critical accounts of Machiavelli, Hobbes, Aristotle, and Plato, as well as various Christian thinkers have brough forth despotic ideas in the form, for example, of brutal Machiavellianism, of Hobbes's justifications for the rule of one, of Plato's reasoning that denied slaves the right of natural defense, and of the Christian teachings that equated heresy with treason. Such ideas, Montesquieu shows, inform such revered European institutions as the French monarchy and the Roman Catholic Church. In this new reading of Montesquieu's masterwork, Sullivan corrects the misconception that it offers simple, objective observations, showing it to be instead a powerful critique of European politics that would become remarkably and regrettably prescient after Montesquieu's death, when despotism repeatedly emerged in Europe with virulent intensity. -- from dust jacket.
