| Abstract: | The capability of flavonoids of Artemisia Ordosica kraschen in scavenging hydroxyl radicals was determined using spectrophotometric method.By using IC50 as the index to evaluate the scavenging capability,the relationship between anti-hydroxyl radical activity and structure of the flavonoids was primarily explored.This,hopefully,is to provide scientific background for the development and utilization of Artemisia Ordosica kraschen. |
