乌饭树叶醇提物体外抗氧化活性

Antioxidation activity by extract of ethanol in vitro from Vaccinium bracteatum Thunb

目的:研究乌饭树叶醇提物的体外抗氧化活性。方法:用总抗氧化能力、还原能力、对DPPH自由基清除率来考察其醇提物的体外抗氧化活性大小,并与同浓度的Vc做比较。结果:乌饭树醇提物抗氧化能力比Vc强。结论:乌饭树叶是一种良好的天然抗氧化剂来源。

Objective：Studies on the influence on antioxidant activity by extract of ethanol in vitro from Vaccinium bracteatum Thunb.Method：？It was evaluated by means by reducing power,DPPH· and total antioxidant capacity.Results：Compared with Vc,Vaccinium bracteatum have higher antioxidant activity.Conclusion：Vaccinium bracteatum are effective and multifunctional natural antioxidants and radical scavengers,and are worth further exploiting and utilizing.
