摘要：

In this study, we investigated chemical structure of lycium barbarum polysaccharides and its modulatory effect on oxidative stress in high-fat mice. The polysaccharides mainly contained xylose and glucose. Little amount of rhamnose, mannose and galactose was observed. The lycium barbarum polysaccharides had IR bands at 800-1200 cm(-1), 1450-1800 cm(-1), 2500-3000 cm(-1), and 3200-3600 cm(-1), which were distinctive absorptions of polysaccharides. Rats are fed with high-fat diet for 2 months. Results showed that blood and liver antioxidant enzymes activities and GSH level in model mice significantly decreased, and MDA level significantly increased (P < 0.01) compared to normal control mice. Administration of lycium barbarum polysaccharides significantly increased antioxidant enzymes activities and decreased MDA level in mice (P < 0.01) compared to model group. (C) 2010 Elsevier B.V.
