초록

Three flavonoids, quercetin, taxifolin, and kaempferol were isolated from the woods of Liriodendron tulipifera. Their structures were determined by spectral analysis. Based on 1, l-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity method, the antioxidative activities of three isolated compounds and their acetates were measured in order to search for natural antioxidants. The IC50 of quercetin (1), taxifolin (2), and kaempferol (3) were 3.6, 3.9, and 4.1 ㎍/㎖, respectively.
