Antioxidant Properties and Correlation with Chemical Components in Selenium-Enriched Rape Powder
摘要
Abstract
This work aims to study the in vitro antioxidant activity of selenium-enriched rape powder extract and its correlation with basic chemical components.The results showed that compared with regular rape powder extract,selenium-enriched rape powder extract contained more nitrogen compounds,polyphenols,flavonoids,total selenium and polysaccharide-bound selenium,and had higher Fe3+reducing power,1,1-diphenyl-2-picrylhydrazyl(DPPH),2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS)radical cation,and hydroxyl free radical scavenging activity.Correlation analysis showed that the antioxidant activity was positively correlated with nitrogen compounds,total sugar,polyphenols,flavonoids,saponins,polysaccharides,total selenium,and polysaccharide-bound selenium.Partial correlation analysis showed that the antioxidant activity was only significantly or highly significantly positively correlated with polysaccharides and polysaccharide-bound selenium,which indicated that the difference in antioxidant activity between the two rape powder extracts may be mainly caused by the differences in polysaccharides and polysaccharide-bound selenium contents.In conclusion,there are differences in the basic chemical compositions of selenium-enriched and regular rape powder extracts,and selenium-enriched rape powder extract has a higher in vitro antioxidant activity.Polysaccharide-bound selenium was the major antioxidant component.关键词
