苦荞麦多糖清除DPPH自由基的作用
Study on Scavenging DPPH Radical Activity with Polysaccharide in Tartary Buckwheat
摘要
Abstract
Aimed at the further exploration of the polysaccharide in Tartary Buckwheat resource, a study of the antioxidant action of polysaccharide in Tartary Buckwheat is made. The activity component is extracted with water. Using the assay system of DPPH, the antioxidant activities of the polysaccharide in Tartary Buck-wheat were studied and compared with those of VE and assorbic acid. Results shows that the extracts of the polysaccharide in Tartary Buckwheat could inhibit lipid peroxidation and scavenge active oxygen free radi-cals. The elimination of the density of the polysaccharide in Tartary Buckwheat (21.764µg/mL) was attained by 24.85%, and remarkable exceeded the same density VE and assorbic acid. The polysaccharide in Tartary Buckwheat extracts showed strongest inhibitory effect on the antioxidation of superoxidized anionic and lipid peroxidantion.关键词
