ABSTRACT
AIM:
To study the optimum technological parameters for extraction of Astragalus polysaccharides by ultra-high pressure extraction.METHODS:
Measured concentration of total astragalus polysacharides served as the marker,the design of uniform distribution was applied to evaluating the ultra-high pressure extration efficiency in comparison with reflux and ultrasonic extraction efficiency.RESULTS:
The optimal parameters of ultra-high pressure extraction was as follows 350 MPa pressure,60 mL/g ratio of solvent to solid material,5 h soaking time,2 min extraction time.Under the conditions,the high yield was up to 24.2 %.CONCLUSION:
Ultra-high pressure extraction has a series of advantages,such as higher yield,less impurity,easier separation-purification,shorter extraction time and lower energy input.
