| Abstract: | The antioxidation activity of Desmodium styracifolium,Desmodium triflorum and Desmodium gangeticum were studied by photometric method and ESR method.The scavenging percentage of the three plants to hydroxyl radical are 60.7%,67.5% and 78.4%,to superoxide radical are 87.5%,80.6% and 74.2%,to free radical of cigarette smoke are 21.1%,31.6% and 17.0%,inhibitory effect on lipid peroxidantion are 79.4%,85.7% and 71.6% respectively. |
