Abstract
Objective To study antioxidant effect and synergism of angustifolia polyphenol and common antioxidants.Methods The antioxidant capacity of angustifolia polyphenol,VC,tea polyphenol and TBHQ was examined through DPPH,hydroxy radical and superoxide anion reacting systems.Results The scavenging effect on hydroxy radical and DPPH of angustifolia polyphenol was stronger than other antioxidants when the concentration of angustifolia polyphenol was 0.5 mg·ml-1 respectively.The scavenging effect on free radicals was greater than the algebra sum of single antioxidant when synergism of angustifolia polyphenol with VC,tea polyphenol and TBHQ.Conclusion There is synergism between angustifolia polyphenol and other antiaxidants;Angustifolia polyphenol has better antioxidant activity as a scavenger of free radicals.
