Extraction and Antioxidant Activity of Polysaccharides fromCimicifuga foetida

WU Ya

Abstract

The extraction of polysaccharide fromCimicifuga foetidaand its effect of removal of hydroxyl radicals was studied.The crude Polysaccharide was extracted fromCimicifuga foetidausing 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.
