摘要: The water-soluble intra-polysaccharides WIPS1 and water-soluble extra-polysaccharides WEPS1 were isolated from Isaria farinosa B05 through ethanol precipitation and get permeation chromatography (GPC). Their characteristics were determined by chemical analysis, gas chromatography, GPC and IR spectroscopy. The results show that WIPS1 contained 90.3% carbohydrate, 8.00% uronic acid, 7.15% protein and three kinds of monosaccharides including mannose, galactose and glucose with a molar ratio of 8.0:4.8:1.0. WEPS1 contained 93.4% carbohydrate, 8.06% uronic acid, 4.40% protein and three kinds of monosaccharides including mannose, galactose and glucose with a molar ratio of 21.6:4.7: 1.0. WIPS1 and WEPS1 had a molecular weight of 42 and 208 kDa, respectively. The in vivo tests in mice indicate that WIPS1 and WEPS1 had significant antitumor and antioxidative activities to some extent.
