| Abstract: | Objective To evaluate the antioxygenation of soybean isoflavone.Methods The antioxygenations of soybean isoflavone,vitamin C and rutin were compared on the base of the elimination tests of DPPH.free radical and hydroxide free radical as well as the oxidation resistance test of linoleic acid.Results Soybean isoflavone could scavenge both of free radicals above.Comparable with rutin,it had a better effect on the elimination of hydroxide free radical.Conclusion Soybean isoflavone is a good scavenger for hydroxide free radical. |
