Studies on effects of scavenging free radicals by cactus polysaccharide

Jinfeng Zhu

Abstract

Extraction of water-soluble polysaccharide in Cactus as well as·OH induced by Fenton reaction and O-_2· induced by ammonium peroxydisulfate/N,N,N’,N’-tetramethylethanediamine(AP-TEMED)were studied.The results shows: the extractive ratio of polysaccharides by water was 2.821%,it's purity was 24.76 1.20%.After the extracts was precipitated by alcohol,raw polysaccharides of 77.52% 1.19% purity were obtained.The capacity of scavenging free radicals of cactus polysaccharides appears linear connections with the concentration.The scavenging ratios of OH and O-_2 free radicals by 1000 mg/L polysaccharides solutions were 63.00% and 57.06%,respectively.
