Abstract

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.

Key words: Vaccinium Bracteatum Thunb, flavone, identification, purification, freeradicle, scavenge
