【摘要】 通過采用化學法,分別測定了猴頭菇多糖、香菇多糖、銀耳多糖、雞腿菇多糖、灰樹花多糖及香菇復合多糖、灰樹花復合多糖體外抗氧化活性。結果表明,0.5 mg.mL-1的猴頭菇多糖、香菇多糖、銀耳多糖、雞腿菇多糖、灰樹花多糖與復合多糖能夠不同程度地清除DPPH.自由基、羥自由基(.OH)和超氧陰離子自由基(O2-.)能力,具有較好的抗氧化活性,而香菇復合多糖和灰樹花復合多糖的總體抗氧化活性優(yōu)于其組成單糖,其中以灰樹花復合多糖對自由基的清除能力最強,其清除率分別為(89.5±1.3)%、(62.4±0.6)%、(47.9±1.0)%。
【Abstract】 In this study,the antioxidant activities of hericium erinaceus polysaccharides,lentinan,tremella polysaccharides,grifolan,coprinus comatus polysaccharides and their compound polysaccharides in vitro were examined.It was found that these polysaccharides(0.5 mg·mL-1) all had been shown to display significantly antioxidant properties,decreased not(1,1-diphenyl-2-picrylhydrazyl radicals and hydroxyl radicals,but also superoxide anion ridicals with different degrees.These results clearly suggested th...
