摘要

The reaction rate constants and transient spectra of 11 flavonoids and 4 phenolic acids reacting with e~aq~- at neutral pH were measured. The results suggest that C_4 keto group is the active site for e~aq~- to attack on flavonoids and phenolic acids, while the o-dihydroxy structure in B-ring, the C_2,3 double bond, the C_3-OH group and glucosylation have little effects on the e~aq~- scavenging activities.
