  • The 1,1-diphenyl-2-picrylhydrazyl（ DPPH） system and phenanthroline-Fe2+ reaction system were used to estimate the activity of the crude polysaccharide（ cAMP）,the partially purified polysaccharide（ AMP）,and two purified polysaccharides（ AMP-Ⅰ,AMP-Ⅲ） from Allium macrosttemon Bge. against the free radicals.The results indicated that four types of Allium macrosttemon polysaccharides had the ability to scavenge DPPH radicals and hydroxyl radicals. The scavenging effects increased with the concentration. The cAMP had the highest scavenging effect on the free radicals,whereas AMP and the lower molecular-weight polysaccharide（ AMP-Ⅰ） had similar scavenging effect on the radicals.

Abstract: The 1,1-diphenyl-2-picrylhydrazyl（ DPPH） system and phenanthroline-Fe2+ reaction system were used to estimate the activity of the crude polysaccharide（ cAMP）,the partially purified polysaccharide（ AMP）,and two purified polysaccharides（ AMP-Ⅰ,AMP-Ⅲ） from Allium macrosttemon Bge. against the free radicals.The results indicated that four types of Allium macrosttemon polysaccharides had the ability to scavenge DPPH radicals and hydroxyl radicals. The scavenging effects increased with the concentration. The cAMP had the highest scavenging effect on the free radicals,whereas AMP and the lower molecular-weight polysaccharide（ AMP-Ⅰ） had similar scavenging effect on the radicals.
