Abstract:

Ultra high pressure (UHP) technology was adopted to extract polysaccharides from Cordyceps militaris (L.ex Fr.) Link at normal temperature. The extraction of polysaccarides by UHP technology was optimized to obtain the maximum yield of polysaccarides by single-factor method and orthogonal array design. A polysaccharide yield of 10.13% was found under the optimized conditions for the extraction of polysaccarides from Cordyceps militaris (L.ex Fr.) Link as follows: extraction for 5 min using 45% as the extraction solvent at 400 MPa with the material/liquid ratio of 1:35 (g/ml). Polysaccharides can be extracted rapidly and effectively by this method without losing their physiological activity, thereby providing a novel and robust approach for extracting active components from Cordyceps militaris (L.ex Fr.) Link.

Key words: ultra high pressure technology, Cordyceps militaris (L.ex Fr.) Link, polysaccharides
