Abstract
The water-soluble polysaccharide (BCPS-1) was isolated from Bupleurum chinense DC. BCPS-1 (Mw = 29 kDa) was composed of Ara; Gal; Glc with a molar ratio of 2.1:2.5:1. According to FT-IR, partial acid hydrolysis, periodate oxidation and Smith degradation, methylation and GC-MS analysis, the results indicate BCPS-1 had a backbone of (1→5)-linked Ara, (1→4)-linked Gal and (1→3)-linked Gal residues with occasionally branches at O-6. The branches were composed of (1→4)-linked Glc, and terminated with Gal residues. The in vitro antioxidant activity evaluated by DPPH radical scavenging method showed that BCPS-1 had a significant antioxidant effect in a concentration-dependent manner.
