Study on extraction of polysaccharides from Agaricus blazei Murrill by microwave

The optimization of extraction technology of polysaccharide from Agaricus blazei Murill by microwave method was performed.With the index of polysaccharide extraction rate, orthogonal test was designed to investigate the optimum technology parameters, including granularity (mesh) , the ratio of solid to liquid, microwave power and extracting time.Optimum extraction parameters were as follows:granularity 60 mesh, the ratio of solid to liquid 1:80 (g/mL) , microwave power 640W and extracting time 8min.Under these conditions, the extraction yield of crude polysaccharide was 9.04%.The newly developed method was simple and efficient.
