中文摘要:

研究了一种从保健口服液中提取并纯化后的真菌复合多糖的体外抗氧化活性(还原力、对羟自由基和DPPH自由基的清除能力),并与复合多糖单一成分进行比较。结果表明:在实验浓度范围内,各真菌多糖抗氧化活性均随着多糖质量浓度增加显示出稳定增长。相同质量浓度下,真菌复合多糖的抗氧化活性高于竹荪多糖及虫草多糖,但较香菇多糖的活性低或相当。表明在考虑药效和经济成本平衡的前提下,真菌复合多糖具有更高的体外抗氧化活性。

英文摘要:

In this manuscript,the antioxidant activity(the reducing power,the ·OH and DPPH· eliminate ability) of a combined fungus polysaccharide extracted from a healthy oral liquid was studied in vitro and compared with raw materials.The results demonstrated that the antioxidant activity of all fungi polysaccharides showed stable growth along with the increasing concentration in the experiment.With the same concentration,the antioxidant activity of the polysaccharide compounds was higher than that of the polysaccharides extracted from Dictyophoraindusiataand CordycepsCephalosporium Mycelia,but was lower than or equal to the activity of lentinan.Therefor the combined fungus polysaccharide has greater health care function when consider the effect and the cost meanwhile.
