Application of water extraction and microwave-assisted extraction method in the extraction of polysaccharides in cordyceps militaris mycelia

Objective:To investigate the method applied in the extraction of polysaccharides in Cordyceps militaris mycelia. Methods:Water-extraction method and microwave-assisted extraction method were applied in the extraction of polysaccharides. The content of polysaccharides in mycelia was determined by phenol-vitriol method. Results:The coarse polysaccharides extractive rate of waterextraction method was 22.26% in Cordyceps militaris mycelia,and the rate of water-extraction method was 15.16%. Conclusions:The extractive rate of water-extraction method is higher than the rate of microwave-assisted extraction method. But the technology of waterextraction method was complex and time consuming. The technology of microwave-assisted extraction method was simple and speedy.
