| Abstract: | Spectrophotometric method was adopted to determine the activity of several natural flavonones from medicinal plant in scavenging superoxide anion radical（O2^-·）. The relationship between the activity of the flavonones in scavenging （O2^-·） and their structure was primarily explored. The present research, hopefully, is to provide scientific background for the develop ment and utilization of natural antioxidants. |
| Keywords: | flavonone superoxide anion radical activity spectrophotometry determination |
