Opis

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

Ronald Ross Watson, PhD, is Professor of Health Promotion Sciences at the University of Arizona, Mel and Enid Zuckerman College of Public Health. Dr. Watson 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 the United States 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 as a Lt. Colonel. He is a distinguished member of several national and international nutrition, immunology, and cancer societies. Dr. Watson's career has involved studying many lifestyle aspects for their uses in health promotion. He has edited over 100 biomedical reference books and 450 papers and chapters. His teaching and research focuses on alcohol, tobacco, and drugs of abuse in heart function and disease in mouse models.
