新疆药用植物黑桑的抗氧化性
Antioxidant Activity of Medicine Mulberry (Morus nigra) in Xinjiang
摘要
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.关键词
