Abstract:
Extraction and isolation of cordycepin from the deserted solid medium of cordyceps militaris by soxhlet Extraction and ion exchange chromatography was studied. The soxhlet extraction showed that water was better than ethanol for the extraction of the cordycepin. The orthogonal test of ion exchange chromatography showed the main influential factors were flow rate of elution and ratio of material to water. The optimal ratio of material to water, the flow speed and the pH value were also confirmed to be 1:16, 3.5 and 1drop/2second, respectively.
