Polyphenols in Plants: Isolation, Purification and Extract Preparation provides insight into how the polyphenols that occur naturally in plants can be affected during growth and development, and then effectively removed and optimized, before being implemented in food production.

Historically plants have been the major sources for drugs and health promotion. There are a small number of nutrients. However, the growing focus is on the very diverse, complex ring structures, polyphenols that are not nutritious. To study or use them in patient treatment the polyphenols need to be isolated, identified, and purified for use and study. This book will bring together experts that will update their continuing study of ways to isolate and purify polyphenols as well as determine their structures and composition. In addition, some will update their previous summaries with new research by others as well as themselves.

Plant scientists and dietary supplement producers will be particularly interested in assessing polyphenol content and factors impacting their composition, to select sources and regulate environmental conditions affecting yield for more consistent and functional dietary supplements.

  • Fully revised and updated with 12 new chapters including extraction optimization, additional plant varieties and recent technology advances
  • Develops understanding of isolation, characterization and identification of critical polyphenols vital to industrial development as therapies
  • Defines conditions of growth affecting the polyphenol levels
  • Describes assay and instrumentation techniques critical to identifying and defining polyphenols, vital to researchers and business development
  • Provides insights into potential dangers and importance to the dietary supplement industry, government regulators and lay public users

Watson, Ronald Ross
Ronald Ross Watson PhD is a professor of Health Promotion Sciences in the University of Arizona Mel and Enid Zuckerman College of Public Health. He was one of the founding members of this school serving the mountain west of the USA. He is a professor of Family and Community Medicine in the School of Medicine at the University of Arizona. He began his research in public health at the Harvard School of Public Health as a fellow in 1971 doing field work on vaccines in Saudi Arabia. He has done clinical studies in Colombia, Iran, Egypt, Saudi Arabia, and USA which provides a broad international view of public health. He has served in the military reserve hospital for 17 years with extensive training in medical responses to disasters as the chief biochemistry officer of a general hospital, retiring at a Lt. Colonel. He published 450 papers, and presently directs or has directed several NIH funded biomedical grants relating to alcohol and disease particularly immune function and cardiovascular effects including studying complementary and alternative medicines. Professor Ronald Ross Watson was Director of a National Institutes of Health funded Alcohol Research Center for 5 years. The main goal of the Center was to understand the role of ethanol-induced immunosuppression on immune function and disease resistance in animals. He is an internationally recognized alcohol-researcher, nutritionist and immunologist. He also initiated and directed other NIH-associated work at The University of Arizona, College of Medicine. Dr. Watson has funding from companies and non-profit foundations to study bioactive foods' components in health promotion. Professor Watson attended the University of Idaho, but graduated from Brigham Young University in Provo, Utah, with a degree in Chemistry in 1966. He completed his Ph.D. degree in 1971 in Biochemistry from Michigan State University. His postdoctoral schooling was completed at the Harvard School of Public Health in Nutrition and Microbiology, including a two-year postdoctoral research experience in immunology. Professor Watson is a distinguished member of several national and international nutrition, immunology, and cancer societies. Overall his career has involved studying many foods for their uses in health promotion. He has edited 120 biomedical reference books, particularly in health and 450 papers and chapters. His teaching and research in foods, nutrition and bacterial disease also prepare him to edit this book. He has 4 edited works on nutrition in aging. He has extensive experience working with natural products, alcohol, exercise, functional foods and dietary extracts for health benefits and safety issues, including getting 12 patents. Dr. Watson has done laboratory studies in mice on immune functions that decline with aging and the role of supplements in delaying this process as modified by alcohol and drugs of abuse.
