| Summary |
Water Extraction of Bioactive Compounds: From Plants to Drug Development draws together the expert knowledge of researchers from around the world to outline the essential knowledge and techniques required to successfully extract bioactive compounds for further study. The book is a practical tool for medicinal chemists, biochemists, pharmaceutical scientists and academics working in the discovery and development of drugs from natural sources. The discovery and extraction of bioactive plant compounds from natural sources is of growing interest to drug developers, adding greater fuel to a simultaneous search for efficient, green technologies to support this. Particularly promising are aqueous based methods, as water is a cheap, safe and abundant solvent. Water Extraction of Bioactive Compounds: From Plants to Drug Development is a detailed guide to the fundamental concepts and considerations needed to successfully undertake such processes, supported by application examples and highlighting the most influential variables. Beginning with an introduction to plants as sources of drugs, the book highlights the need for a move towards both more rational and greener techniques in the field, and presents multiple innovative water-based strategies for the discovery and extraction of bioactive constituents of botanicals. A broad range of available techniques are reviewed, including conventional and pressurized hot water extraction techniques, intensified processes such as microwave-assisted, ultrasound-assisted processes, and enzyme assisted extraction, and processes using combined techniques |
