| Abstract: | Objective To study the hydroxyl radical scavenging and DNA damage protecting activities of ether extract, acetoacetate water extract of Rosa davurica pall. Methods The hydroxyl radical scavenging action and DNA damage protection action were determined by CuSO 4 VitC H 2O 2 Yeast and CuSO 4 VitC H 2O 2 phen DNA chemiluminescence systems respectively. Results Extract liquid showed hydroxyl radical scavenging and DNA damage protection activities in dose dependent manners. Conclusion Extract liquid have the effect of hydroxyl radical scavenging and anti DNA damage. |
