Abstract

The effect to scavenge DPPH radical,hydroxyl radical and superoxidant radical by buckwheat sprouts extractive is determined by colorimetry and chemical luminescence method.The experiment shows that the buckwheat sprouts extractive possess powerful effect on scavenging DPPH radical and hydroxyl radical,yet weak on superoxidant radical.The IC50 value of scavenging DPPH radical is 0.064mg/mL and the rate of scavenging hydroxyl radical is 57.65% when the alcoholic extractive concentration of buckwheat sprouts was 0.15mg/mL.
