Abstract:Codonopsis was extracted with hot water at 90 °C , precipitated by alcohol. The protein in the extract was removed by zinc sulphate. The resulting solution was passed through an absorbent column packed with polyerde. The column was then eluted with hot water (60 °C ), the eluate was precipitated by alcohol and dried in vacuum, codonopsis pilosula polysaccharide (CPPS) was obtained. The inhibitable effects of CPPS on superoxide anion free radical and hydroxyl free radical were measured by spectrophotometry. By the results, the CPPS was shown possessing scavenging action on O -· 2 and OH ·.
Keywords:codonopsis pilosula polysaccharide  hydroxyl free radical  Superoxide anion free radical
