A water-soluble polysaccharide from Dioscorea bulbifera (Dioscoreaceae) rhizome was isolated by extraction with water extract and alcohol precipitate and further purified by DEAE cellulose-52 chromatography to yield DBP-1 and DBP-2. The total yield rate of the polysaccharides was 4.3 %. Molecular weights were determined by high performance gel permeation chromatography (HPGPC). The molecular weights of DBP-1 and DBP-2 were 122435Da and 5180Da, respectively. The antioxidant activity of DBP-1 and DBP-2 were evaluated with the scavenging abilities on 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radicals in vitro, and the results indicated that DBP-1 and DBP-2 had good antioxidant activity. These results suggested that the polysaccharides (DBP-1 and DBP-2) obtained from the Dioscorea bulbifera might be suitable for use as functional foods and potential therapeutic agents for human aging.
Keywords:plant polysaccharide; Dioscorea bulbifera; puri?cation; antioxidant activity
