Determination on Kiwi Fruit Root Extraction in Eliminating Free Radical Activeness by Spectrophotometric Method

[Objective] The aim was to search a simple and effective way for hydroxyl radicals in vitro test.[Method] Using the spectrophotometric method,scavenging effect of kiwi fruit root extraction solution on the hydroxyl free radical was determined.and the control experiment with vitamin C was carried on.[Result] The study showed that kiwi fruit root extraction solution and the vitamin C in eliminating hydroxyl free radical′s function had the very good quantity effect relations.[Conclusion] Spectrophotometry method could be used to scavenge hydroxyl free radicals.
