| Abstract: | Objective： To study antioxidant activity of polysaccharide extracted from three different solvents of Gonostegia hirta （BL.） Miq. Method： The experiment tests the antioxidant activity of three kinds of polysaccharides by hydroxyl radical scavenging test. Result： The result shows that the polysaccharide which is extracted by water possesses the best reducing ability in the same concentration, and that polysaccharides obtained by water extraction and alkaline extraction are proportional to their concentration on eliminating hydroxyl radical. Conclusion： Polysaccharide has effective antioxidant activity, so it has great development and application of value in food and medicine industry. |
