摘要

Dihydromyricetin-zinc(Ⅱ) complex was synthesized. The scavenging activity of DPPH radical, hydroxyl radical, superoxide anion radical and alkane radical by dihydromyricetin-zinc(Ⅱ) complex were determine, moreover compared with Vc. The results showed that dihydromyricetin-zinc(Ⅱ) complex possessed strong scavenging activities on DPPH, hydroxyl radical, superoxide anion radical and alkane radical with correspounding maximum scavenging rate 74%, 70% , 65% and 50% at the concentration from 0.1 mmol/L to 0.5 mmol/L, respectively, which were higher than Vc. These results suggested that dihydromyricetin-zinc(Ⅱ) complex would be an effective free radical scavenger.
