Microwave-assisted extraction of polysaccharides from Camptotheca acuminate (CAPs) was optimized by response surface methodol. The optimal parameters were as follows: microwave power, 600 W; liquid-solid ratio, 40:1 g/mL; extraction time, 14 min; and extraction temperature, 70 °C. Under these conditions, the yield of CAPs reached up to 8.61%. CAP-3, an acidic polysaccharide with a mol. weight of 121.34 kDa, was separated and purified from CAPs, which was only composed of glucose and mannose. CAP-3 exhibited strong antioxidant activity against DPPH (IC50: 0.78 mg/mL), hydroxyl radicals (IC50: 0.84 mg/mL) and also showed synergistic antioxidative effect with ascorbic acid in vitro. Meanwhile, CAP-3 could protect plasmid DNA from oxidative damage. Moreover, CAP-3 could improve immunomodulatory activity of RAW264.7 cells through promoting the phagocytosis and nitric oxide release. Therefore, CAP-3 had a strong potential in functional food, pharmaceuticals and cosmetics industries.
International Journal of Biological Macromolecules published new progress about Antioxidants. 3458-28-4 belongs to class alcohols-buliding-blocks, and the molecular formula is C6H12O6, Product Details of C6H12O6.
