Abstract

AIM: To determine the contents of flavonoids and its scavenging effect of flavonoids in Evodia rutaecarpa on hydroxyl radical. METHODS: The flavonoids were determined by Al(NO_3)_3-NaNO_2 spectrophotography method, with sodium salicylate captured the hydroxyl radical based on Fenton reaction to make development, its absorbance was measured at 510 nm and adopted as clearance of scavenging effect on hydroxyl radical. RESULTS: The contents of flavonoids were within 29.39 mg·g -1 - 59.64 mg·g -1 from Evodia rutaecarpa and its different processed product. CONCLUSION: The flavonoids in Evodia rutaecarpa showed better effect on scavenging hydroxyl radical.
