Technical Abstract: A new age of nutrition research has begun with increased interest in the role that phytochemicals contained in foods in mitigating or preventing the development of chronic diseases such as cancer, heart disease, and other age related problems. While a number of foods, for example soy and broccoli, have been identified as having health promoting effects, the exact chemical and physiological roles of their phytochemical components have not been fully delineated. Part of the problem is a lack of significant quantities of pure phytochemicals for use in nutritional studies, both individually and in mixtures. This USDA research project’s focus is to develop methods for the purification of significant quantities of phytochemicals from soy, crucifers, and other legumes to enhance the study of the interaction of a variety of phytochemicals in biological systems. Many of these phytochemicals are normally present in low concentrations and in a glycoside form in the plant tissues, which can be extracted and purified using water and alcohol mixtures. New heat/pressure extraction methods can be used to enhance the yield and separation of these components. This methodology has been applied to the separation and purification of isoflavones and saponins from soy.
