猴头菌液体 固体发酵产物多糖抗氧化活性研究

摘要

通过还原能力的测定和DPPH·,O2-·,·OH清除率的测定,体外抗氧化试验结果表明,猴头菌多糖具有较强的抗氧化活性,在试验的3种多糖中,抗氧化能力依次为固态发酵产物多糖HeP3＞液体发酵菌丝体多糖HeP1＞发酵液多糖HeP2.%Through determinations of reducing capacity,DPPH· free radical scavenging rate,O2-·scavenging rate,and ·OH scavenging rate,the in-vitro antioxidant test results have shown that the fermentation broth polysaccharide of Hericium erinaceus has a strong ability of scavenging the free radical.Among the three kinds of polysaccharides in this experiment,the antioxidant capacity of HeP3＞HeP1＞HeP2.
