The Antioxidation Activity in Vitro of Phloridzin Isolated from Apple Pomace

摘要

After the phloridzin crude solution was absorbed by D-101 resin,the resin was eluted by 50％,60％,70％,80％ and 90％ ethanol solution in sequence,and phloridzin crude solution,50％ ethanol elution solution and 90％ ethanol elution solution were analyzed by HPLC for component.The antioxidation activity in vitro was tested for 90％ ethanol elution solution.The result shows that the component in high content of ethanol elution solution is more simple; phloridzin isolated by resin has good capacity on scavenging HO·,O2-·and DPPH·,and shows good doses-response relationship.
