[Objective] To study the scavenging activity of Huidouba extracts on free radical in vitro.[Method] Taking Vc as control,the scavenging effects of 3 intermediates(HDB-1,HDB-2 and HDB-3) of Huidouba extracts on superoxide radical,hydroxyl radical,and DPPH radical at three different extraction stages were compared.[Result] Among three intermediates of Huidouba in different extraction stages,the scavenging effects of HDB-1 on superoxide radical,hydroxyl radical,and DPPH radical were strongest,which reached 36.2%,31.1% and 35.0% respectively in this study.There were no significant differences between HDB-2 and HDB-3 on scavenging activity.[Conclusion] The extracts of Huidouba in this study have the potential to be developed as natural radical scavenger.
