Study on extraction technology and antioxidative activity of polysaccharides produced by Lachnum hyalopus
Extraction of polysaccharide from Lachnum hyalopus with microwave and its scavenging capacity of superoxide anion radical and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical were studied. The results indicate that the optimum conditions for extraction of polysaccharide were as follows: microwave...

| description | Extraction of polysaccharide from Lachnum hyalopus with microwave and its scavenging capacity of superoxide anion radical and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical were studied. The results indicate that the optimum conditions for extraction of polysaccharide were as follows: microwave power was 150 W with ratio of liquid to material at 80 and 3 min of extraction time. Under above conditions, the polysaccharide yield was up to 12.05%. Meanwhile, the scavenging effects of the polysaccharide on O<sub>2</sub><sup>-</sup> and DPPH free radicals were both significant, which the scavenging effects on the O<sub>2</sub><sup>-</sup> radical reached 86, 67% with 100 mg·L<sup>-1</sup> polysaccharide, and the clearance rate of DPPH free radical reached 10.79% with 10 mg·L<sup>-1</sup> polysaccharide. So it can be concluded that the polysaccharide displayed obvious antioxidant activities. |
