| 内容記述 | The radical-scavenging activity of naturally occurring polyphenols has attracted considerable interest with regard to prevention of diseases induced by oxidative stress . However, very little is known about the structure-activity relationships in the radical-scavenging reactions by polyphenolic antioxidants. In this study, we examined the dynamics of the scavenging reaction of cumylperoxyl radical by four polyphenolic flavones, quercetin, luteolin, kaempferol, and apigenin, in propionitrile at 203 K by using the electron spin resonance (ESR) technique. The results obtained in this study suggest that not only the OH group at C-3' position on the B ring but also that at C-3 position on the C ring plays an essential role in the radical-scavenging reaction. | |||||
