Antioxidant and immunological activities of polysaccharides from Gentiana scabra Bunge roots. 作者:Wang, Zhanyong; Wang, Chenyu; Su, Tingting; Zhang, Jing Carbohydrate polymers 卷:112 页:114-8 DOI:10.1016/j.carbpol.2014.05.077 出版年:2014-Nov-4 (Epub 2014 Jun 04) 摘要 Two polysaccharide fractions, GSP I-a and GSP II-b, were isolated from Gentiana scabra Bunge roots. Both GSP I-a and GSP II-b comprised seven monosaccharides: fructose, mannose, rhamnose, galacturonic acid, glucose, galactose, and fucose. Ultraviolet and infrared analyses show that GSP I-a and GSP II-b are proteoglycans. In vitro evaluation of the antioxidant activity suggests that GSP I-a and GSP II-b scavenge 1,1-diphenyl-2-picrylhydrazyl radicals. However, the scavenging activity of the latter is stronger than that of the former. GSP I-a and GSP II-b have relatively low reducing powers and scavenging activities toward superoxide anions and hydroxyls. GSP I-a and GSP II-b significantly increase lymphocyte proliferation when lipopolysaccharide is used as a mitogen for lymphocytes, but only GSP I-a can significantly increase lymphocyte proliferation within the test-dosage range when concanavalin A is used as a mitogen.
