Abstract: The purpose of the experiment is to optimize the extraction technology of the Cordycepin from Cordyceps militaris, the mathematical regression model was established about the dependent variable (the extraction rate of Cordycepin) and independent variables (the proportion between the raw materials and the solution,,time,the power) through Box-Benhnken center composite design and response surface methodology, As a result, the best extraction technology of the Cordycepin from Cordyceps militaris as follows: the proportion between the raw materials and the solution 1:26.84, power329.57W, time40.25min, under such conditions, the extraction rate could be up to 4.58454‰
