Abstract:
Objective To optimize the technological conditions of polysaccharide extraction from Elaeagnus angustifolia L. by enzymatic-assisted ultrasonic. Methods The effects of different enzymes, enzymolysis temperature, enzyme dosage, enzymolysis time, material-water ratio, crushing degree, ultrasonic time and ultrasonic temperature on the extraction rate of Elaeagnus angustifolia L. polysaccharide was analyzed. Results The optimal technological condition was as follows:1.5% cellulase, 1.5% pectic enzyme, enzymolysis time 40 min, enzymolysis temperature 55 ℃, ultrasonic time 25 min, ultrasonic power 400 W, material- water ratio 1∶30, and temperature 60 ℃. In these conditions, the extraction efficiency of polysaccharide was 12.35%. Conclusion The process is simple and practicable, and can be used for the extraction of Elaeagnus angustifolia L. polysaccharide.
