摘要: 以透明质酸为参照,分别在两种相对湿度条件下考察了四角蛤蜊多糖的吸湿和保湿性及其随时间的变化情况,结果表明,四角蛤蜊多糖具有一定程度的吸湿性和较持久的保湿性,并且有一定的湿度依赖性;以VC为对照,考察了其羟自由基清除能力、DPPH自由基清除能力以及还原能力,结果显示,四角蛤蜊多糖具有一定的抗氧化性能,尤其对羟自由基的清除能力很强。所以,四角蛤蜊多糖作为天然的保湿剂和抗氧化剂有一定的应用前景。Abstract: Moisture absorption and moisture retention of Mactra Veneriformis polysaccharide were investigated under two kinds of humidity conditions with hyaluronic acid as a reference. The result showed that polysaccharide had a certain degree of moisture absorption and long lasting moisture retention, and a certain degree of humidity-dependent. Taking VCas a referential substance, hydroxyl radical scavenging ability, DPPH scavenging ability and reducing capacity of Mactra veneriformis polysaccharide were studied. The result showed that it had a certain degree of antioxidant capacity, especially the capacity of scavenging the hydroxyl radical. These results clearly established the possibility that Mactra Veneriformis polysaccharide could be effectively employed as type of natural moisturizer and antioxidant.
