| Abstract: | The extraction of polysaccharide from Ci.micifuga foetida and its effect of removal of hydroxyl radicals was studied. The crude Polysaccharide was extracted from Cirnicifuga foetida using hot water-ethanol method. The free radical cleaning effect was studied employing colorimentry method. The results showed that the polysaccharide had the ability to scavenge hydroxyl radicals, which had the dose-effect relationship with the concentration of polysaccharide that was 2.4mg/mL when scavenging 50% hydroxyl radicals. |
