| Abstract: | The scavenging effects in vitro of total flavones of mulberry on 1, 1-diphenyl-2-picrylhydrazyl free radical （ DP- PH^＊ ）, hydroxyl radical （OH^＊）, superoxide radical （O2^-＊）, were studied by urVis spectrum. The results showed that total flavones of Mulberry could be well used in scavenging DPPH^＊ , OH^＊ , and O2^-＊ , and the maximum scavenging rates were 86.10% ,86.02% and 43.64% , respectively. |
