The isolation and identification of flavonoids from onion skin would not only enhance our understanding of the material basis for their biological activities, but could also provide a theoretical basis for the utilization of these compounds in a number of other areas of research.	cache/bjp-26419.pdf	txt/bjp-26419.txt
