Bioavailability of natural phenolic antioxidants in fruits and other plant-derived foods
P
henolic compounds are constituents of many fruits, vegetables and other plant-derived foods and they have attracted a great
deal of public and scientific interest because of their potential anticarcinogenic, antibacterial, anti-inflammatory and other
health-promoting effects as antioxidants and free radical scavengers. A number of epidemiological studies have given evidence
that consumption of fruits and vegetables is correlated with reduced incidence of mortality from cancer and cardiovascular
and neurological diseases. The protection that fruits and vegetables provide against these diseases has been attributed to the
polyphenolic and other antioxidant phytonutrients contained in these foods. Therefore, it is important to isolate, identify and
quantify polyphenolic compounds and their bioavailability in order to understand their critical roles in human health. In this
presentation, the speaker will first report on the progress on the separation, identification and measurement of polyphenols in
various fruits, vegetables, traditional Chinese medicines, tea and other plant-derived foods in the past decade, mainly by GC,
GC-MS, HPLC, HPLC-MS, CE and CE-MS; then further discuss the antioxidant, free-radical scavenger and anticancer capacity
of polyphenols and finally focus on the bioavailability including absorption, subsequent distribution, metabolism and excretion
of polyphenols in human fluids.
Biography
Yuegang Zuo is currently a Full Professor in analytical, environmental and food chemistry and Director of Graduate Programs at Department of Chemistry and
Biochemistry, University of Massachusetts Dartmouth. He received his BS degree in chemistry from Wuhan University in 1982, his MS degree in environmental
chemistry from the Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, in 1984 and his PhD in environmental science from Swiss
Federal Institute of Technology Zurich in 1992. Most of his recent research has focused on separation, identification and quantification of endocrine disrupting
pollutants and phenolic antioxidants in plants and seafood as well as in the related environments and examine their occurrence, sources, distribution, transportation
and fate in the bio-chemosphere. He has published over 80 peer-reviewed papers in prestigious international scientific journals such as Science, ES&T and JAFS.
