| Abstract: | Extracting water soluble polysaccharide of the Physalis alkekengi L.varfrancheti by the methods of warm water extraction and ethanol precipitation the extraction rate was 4.24%, getting the purify polysaccharide by DEAE-32 and Sephadex G-100. This polysaccharide have a concentration-dependent scavenging effect on superoxide anion radical and hydroxyl radical. The EC50 were 0.149mg/mL and 0.277mg/mL. |
