1. process for efficiently concentrating cordycepin is characterized in that this technology may further comprise the steps:

  • A, supersound extraction obtain ultrasonic concentrated solution;

    20~

    30 ℃

    of ultrasonic temperature, the extracting solution mass percentage concentration is 30~

    50% ethanol water, ultrasonic time is 25~

    75min, and artificial Chinese caterpillar fungus and extracting solution mass volume ratio are 1;

    10~

    30kg/L, and the volume ratio of ultrasonic power and extraction pot is 10~

    30kw/m 3B, membrane filtration concentrate;

    Get above-mentioned ultrasonic concentrated solution, the control temperature is below 30 ℃

    , carry out ultrafiltration, it is 20000~

    40000 daltonian polyamide rolled films that ultrafilter membrane adopts molecular cut off, pressure is 0.4~

    0.6MPa, 3~

    5 hours ultrafiltration time obtained the concentrated solution after the ultrafiltration, and volume is 30~

    50% of a ultrasonic concentrated solution.C, lyophilization;

    In temperature≤

    30 ℃

    , vacuum is lyophilization 35~

    40 hours under 5~

    10Pa condition with the concentrated solution after the ultrafiltration.
