摘要: A water-soluble polysaccharide(named MCMP) was isolated from the mycelium with high yield mutation Cordyceps militaris by hot-water extraction, deproteinization by sevage, alcohol precipitation, anion-exchange and gel filtration chromatography CL-6B. The polysaccharide contained mannose, rhamnose, galactose and glucose in a molar ratio of 59.36:1:8.31:39.50, of which the average molecular weight is 8100. In our research, Hep-G2 cells, Hela cells and mesangial cells were chosen to determine the anti-tumor activity of the polysaccharide. The results of MTT assay show that polysaccharides of the mutant strain presented inhibitory activity on the cells proliferation after 48 h incubation.
