Cordyceps militaris polysaccharide was one of the main functional active components of Cordyceps militaris. The antioxidant activity of enzyme were enhanced, the radicals were cleaned up.It prevented or re-duced the effect of oxidative damage caused by radicals. This article summarized the antioxidant activity of Cordyceps militaris polysaccharide from sinensis, mycelial polysaccharide, extracellular polysaccharides from fermentation broth, It offered some ideas and references about further study on antioxidant activity of Cordyceps militaris polysaccharide.%蛹虫草多糖是蛹虫草的主要功能活性成分之一,具有提高机体多种抗氧化酶活力,清除机体产生的过多自由基,有效防止或减轻自由基所导致的氧化损伤等作用.总结了蛹虫草子实体多糖、菌丝体多糖和发酵液胞外多糖三类不同来源的多糖抗氧化活性,旨在为学者们进一步研究蛹虫草多糖的抗氧化活性提供一定的思路和参考.
