| Abstract: | The content of flavones of Ficus.tikoua Bur were determined using UV-vis spectrophotometry. In the meantime, the scavenging hydroxyl free radical(OH.) and superoxide anion free radical(O2.-)of the extracts of Ficus.tikoua Bur were measured through Fenton reaction and pyrogallol autoxidation method. The results showed that the extracts of Ficus.tikoua Bur had a strong capacity on scavenging free radical. The Scavenging rates of hydroxyl free radical were 90.24%,respectively,The inhibition rates of superoxide anion free radical were 50%. |
