乌饭树树叶中黄酮类色素清除活性氧自由基的研究

Scavenging O_2^- · and ·OH of Extracts from the Leaves of Vaccinium Bracteatum Thunb

本文对乌饭树树叶中提取出的色素进行了分离纯化,分离出了四种黄酮类物质。并且对这四种物质清除活性氧自由基的能力进行了研究,发现乌饭树提取物都具有很强的清除自由基能力,清除能力最强的槲皮素和6#提取物的IC50达到了5.9μg/ml左右。

In this article we identified and purified four flavones from the leaves of Vaccinium Bracteatum Thunb. We also studied the functions scavenging O2^-· and · OH of the flavones. We found that all the extracts have low IC50. Quercefin while the 6th extract has had the lowest IC5o. It was around 5.9μ g/ml.
