摘要: 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。

Abstract: In this article we identified and purified four flavones from the leaves of Vaccinium Bracteatum Thunb. We also studied the functions scavenging O•2 and• OH of the flavones. We found that all the extracts have low IC50. Quercetin while the 6th extract has had the lowest IC50. It was around 5.9μgml.
