Activity diversity structure-activity relationship of polysaccharides from lotus root varieties

The in vitro activities of 39 polysaccharides from different parts of 13 lotus root varieties were evaluated and introduced into multiple linear regression analysis to explore the structure-activity relationships using their chromatographic fingerprint features as independent variables. Their 2,2-diphenyl-1-picrylhydrazyl/hydroxyl radical scavenging abilities, ferric reducing antioxidant powers and growth-inhibitory effects against HepG2 and...
