چکیده انگلیسی
The Sulfated polysaccharide was purified through anion-exchange and gel permeation column chromatography. The isolated sulfated polysaccharide from C. corticata contains 84% of carbohydrate, 0% of protein, 19.7% of ash and 29.4% of moisture was found. The carbon, hydrogen, nitrogen and sulfur content as 33.19%, 5.91%, 7.21% and 3.75%. The molecular weight of sulfated polysaccharide was found to be 43 kDa. The sugar was composed of (90.11%), glucose (5.47%), xylose (2.30%) and mannose (2.12%). The structural feature of sulfated polysachharide was studied through FT-IR and 1H NMR spectral analysis. Further the sulfated polysaccharide showed total antioxidant activity of 24.93%-75.21% at 50-250 μg/ml, DPPH free radical scavenging activity of 23.12%-73.01% at 10-160 μg/ml, ABTS scavenging activity of 15.8%-74.5% at 25-125 μg/ml hydroxyl radical scavenging activity 12.87-69.19% at 25-125 μg/ml and superoxide radical scavenging activity 28.10-78.11% at 50-250 μg/ml respectively. The sulfated polysaccharide has shown good antibacterial activity against human pathogen.
