石榴籽多酚的体外抗氧化活性
The antioxidant activity of pomegranate seed polyphenols in vitro
摘要
Abstract
Objective:In order to develop the value of pomegranate seeds and determine the antioxidant activity difference of crude-extracted fluid and purified liquid.Methods:In this paper,the pomegranate seed polyphenols were extracted and purified by organic solvent.Through ABTS method,pyrogallol autoxidation method,Fenton method and DPPH method were used to determine the radical-scavenging ability of pomegranate seed polyphenols.The results showed that both the crude-extracted fluid and purified liquid had strong ability to scavenge ABTS and DPPH free radicals,while weak in scavenging superoxide anion radical and hydroxyl radical.The IC50 values of crude-extracted fluid scavenging ABTS and DPPH free radicals were 37.13,191.82 μg/mL respectively.And that of purified liquid were 29.11,143.26 μg/mL,respectively.The ability of purified liquid to scavenging ABTS free radicals,hydroxyl radicals and DPPH free radical were stronger than crude-extracted fluid.关键词
