Abstract: In order to find a natural antioxidant material, ethanolic extracts of fruits (EEMF), leaves (EEML), branches (EEMB) and roots (EEMR) of medicine mulberry(Morus nigra) were investigated. The results showed that although the medicine mulberry fruits did not have the highest total polyphenol content (0.943 8 mg·mL-1) and total flavonoids content (0.174 7 mg·mL-1) among those organs, the EEMF possessed the strongest antioxidant effect. The abilities of scavenging hydroxyl radicals, scavenging DPPH radicals and inhibiting lipid oxidation reached to 96.46%, 96.83% and 71.14%, respectively. In addition, Fe2+ chelating ability of EEMF was stronger than that of EEMR, EEMB and EEML. Therefore, medicine mulberry fruit can be used to develop a natural and nutritious food additive.

Key words: medicine mulberry, Morus nigra, total polyphenols, total flavonoids, antioxidant activity, Fe2+-chelating activity
