Abstract:
Object To study the technology of supercritical CO_2 extraction of effective components from Dragon's Blood which has the inhibiting function on ?-glucosidase. Methods The influence of the extraction pressure, temperature, time and fluid velocity on surplus extraction rate and the improvement of inhibition was mainly discussed. Results The optimal experimental parameters were 15 MPa extraction pressure, 45 ℃ extraction temperature, 30 kg/h fluid velocity and 2 h extraction time. Conclusion The results show that SFE-CO_2 can enormously increase the surplus extraction rate and the inhibitory activities on ?-glucosidase.
