The Scavenging of Oxygen Free Radical by the Water Extracts of Peony Flowers |
| |
| Abstract: | When added to the generating and detecting systems of superoxide radical (O2-.) and hydroxyl radical(O2-.) ,the water extract of peony flowers inhibited light chemical reduction of nitroblue tetrazolium (NBT)mediated by O2-. and reduced hydroxylation of salicylate at .OH condition. It shows that the water extract ofpeony flowers presented scavenging of oxygen free radical, the water extract of deep red colored flower wasmore effective than that of a light colored flower. |
