Book Description
During the last ten years, several new extraction techniques have been developed that are faster, more automated and use less organic solvents compared to classical solvent extraction techniques. Furthermore, there is a clear trend going towards the use of (and research on) environmentally sustainable methods, which is encouraging for the future. Supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE) are two of the most useful techniques for extraction of non-polar and medium polar solutes from solid and semi-solid samples. These techniques commonly use pressurized carbon dioxide or hot liquids such as water as extraction solvents, respectively. For aqueous samples, stir-bar sorptive extraction (SBSE) has recently been developed. These are some of the techniques that will be described in the proposed symposium series book. Focus will be on the extraction of various compounds from food and agricultural samples in either an analytical or a process-scale point-of-view. Several of the book chapters will compare the different techniques, and describe their advantages and disadvantages. Applications discussed in this book include SFE of biopolymers from distillers dried grains, SFE of lipids from oilseeds, PLE of functional ingredients from plants and herbs, tandem SFE/PLE of acrylamide from potato chips, SFE and PLE of cholesterol and fat from hamster liver, and steam distillation-extraction (SDE) and SBSE of flavors from shitake mushrooms.

Book Description
Natural products are sought after by the food, pharmaceutical and cosmetics industries, and research continues into their potential for new applications. Extraction of natural products in an economic and environmentally-friendly way is of high importance to all industries involved. This book presents a holistic and in-depth view of the techniques available for extracting natural products, with modern and more environmentally-benign methods, such as ultrasound and supercritical fluids discussed alongside conventional methods. Examples and case studies are presented, along with the decision-making process needed to determine the most appropriate method. Where appropriate, scale-up and process integration is discussed. Relevant to researchers in academia and industry, and students aiming for either career path, Natural Product Extraction presents a handy digest of the current trends and latest developments in the field with concepts of Green Chemistry in mind.

Book Description
The main challenge in modern solvent extraction separation is that most techniques are mainly empirical, specific and particular for narrow fields of practice and require a large degree of experimentation. This concise and modern book provides a complete overview of both solvent extraction separation techniques and the novel and unified competitive complexation/solvation theory. This novel and unified technique presented in the book provides a key for a preliminary quantitative prediction of suitable extraction systems without experimentation, thus saving researchers time and resources. Analyzes and compares both classical and new competitive models and techniques Offers a novel and unified competitive complexation / solvation theory that permits researchers to standardize some parameters, which decreases the need for experimentation at R&D Presents examples of applications in multiple disciplines such as chemical, biochemical, radiochemical, pharmaceutical and analytical separation Written by an outstanding scientist who is prolific in the field of separation science

Book Description
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

Book Description
This book coves one of the most important areas in analytical sciences, extraction techniques for organic compounds in environmental and related matrices. This text discusses all of the key stages for analysing a sample for organic compounds from the initial sampling protocols, the range of different extraction techniques for solid, liquid and air samples through to the final chromatographic analysis. The topics covered include: Initial steps for solid, aqueous and air sampling. Extraction techniques for aqueous samples, including LLE, purge and trap, SPE, SPME, SBSE, SDME, membrane microextraction and MPES. Extraction techniques for solid samples, including Soxhlet, 'Soxtec', Shake-flask, sonication, PFE, MAE, SFE and MSPD.
