In this study, response surface methodol. (RSM) was used to optimize the extraction parameters of dandelion root polysaccharide (DRP). Two novel polysaccharides (DRP-2b, DRP-3a) were isolated from dandelion root by graded ethanol precipitation and column chromatog. Structural analyses indicated that DRP-2b, with a mol. weight of 31.8 kDa, was composed of rhamnose, glucuronic acid, glucose, galactose and arabinose, whereas DRP-3a, with a mol. weight of 6.72 kDa, was composed of rhamnose, glucose, galactose and arabinose. The backbones of DRP-2b and DRP-3a were mainly composed of (1 â?5)-linked-a-D-Ara and (1 â?6)-linked-a-D-Glc, resp. In addition, the antioxidant activities and protective effects against H2O2-induced damage in hepatic L02 cells were evaluated. DRP-3a exhibited higher radical scavenging activity than DRP-2b against the DPPH, hydroxyl and superoxide anions. Furthermore, DRP-3a exhibited strong protective effects against H2O2-induced damage in hepatic L02 cells. Thus, DRP-3a could be used as a potential antioxidant in medicine or as a functional food.
