摘要: 以香桃木叶片为材料,60%乙醇提取获得粗多酚样品,并对样品的油脂抗氧化性和自由基清除能力进行研究。结果表明,未经纯化的香桃木粗多酚对油脂抗氧化效果优于BHT和VC等人工合成抗氧化剂;在清除自由基的实验中,相同浓度的香桃木粗多酚对DPPH自由基的清除率为VE的5倍,对羟自由基的清除效果也略优于VC。由此可以预见香桃木粗多酚在精细加工、经纯化后抗氧化效果会更加显著。

关键词: 香桃木, 粗多酚, 抗氧化活性, 清除自由基

Abstract: Crude polyphenols were firstly extracted from leaves of Myrtus communis and their antioxidant activities and free radical scavenging capacities were investigated. The results showed that the crude polyphenol of M. communis exhibited better antioxidant activities than VC and other synthetic antioxidants. In the experiment of scavenging free radicals, at the same concentration, the scavenging activity of polyphenol extracts to DPPH radical was five times of the VE, and the effecton ·OH was than the VC. It can be expected that of purified polyphenol samples will exhibit even better antioxidant activity.

Key words: Myrtus communis, crude polyphenol, antioxidant activity, free radical scavenging capacity
