Dr Rostagno is an analytical chemist based at the University of Campinas, Brazil. His research interests include modern extraction and analysis technqiues and materials, phytochemicals and natural products.
„Natural Product Extraction” is the 21. part within the series of
„RSC Green Chemistry”. The pool of natural products represents a
valuable source for bioactive compounds. On the one hand, important
medicines, foods and cosmetics comprising classical and new
representatives may be obtained by the extraction of different
plants/crops (natural sources), on the other hand, the production
of such chemicals is much more environmentally friendly (“greener”)
than their processment by chemical syntheses due to the concerns of
the negative effects meant by the use of solvents, formation of
by-products and insufficient atomic efficiency. This book gives an
in-depth review of the state-of-the-art techniques for the
extraction and processing of natural products and the factors
influencing the performance of the process. Chapter 1 shows the
possible use and applications of natural products. The extracts
comprise foods, fat, oils and colouring agents. Chapters 2-6
present both conventional (soaking, Soxhlet, distillation with
water and/or steam) and up-to-date (ultrasound- or
microwave-assisted, “accelerated” liquid, or supercritical fluid)
extraction techniques. Then, the recent trends and perspectives for
the extraction of natural products are discussed in a Chapter 7
followed by the possible post-extraction processes (purification,
particle size reduction and formulation) of the extracts. Chapter 9
provides information on the isolation and purification of natural
products by solvent partitioning, adsorption enrichment, membrane
separation, and solid phase extraction, as well as purification by
chromatography and/or crystallization. Chapter 10 deals with the
scale-up of extraction processes, while Chapter 11 discusses the
pressurized fluid-based technologies for natural product
processing. Finally, Chapter 12 provides the reader about the
economic aspects of the scaled-up extraction technologies. The book
incorporates a number or very useful case-studies. This book is
recommended to chemists, chemical-, bio-, food- and environmental
engineers working in the academic or industrial sectors. The book
may be used well in the training of students in green chemical
courses.
