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: To study the antioxidant activity of the extract of Ulva pertussis leaves in vitro. Methods: Total antioxidant capacity and reducing ability of DPPH radical scavenging activity were investigated in vitro antioxidant activity of ethanol extract, and with the same concentration of Vc comparison. Results: The antioxidant capacity of the ethanol extract of O. japonicus was stronger than that of Vc. Conclusion: Ukrainian leaves are a good source of natural antioxidants.
