Abstract: The ultrafiltration technology of separating polysaccharide from Acanthopanax sessiliforous fruits was studied. On the basis of single factor tests, response surface methodology was designed by minitab software 15. The effect of ultrafiltration pressure, time, temperature and feeding concentration on membrane flux was studied. The results showed that the optimum ultrafiltration conditions were ultrafiltration pressure of 0.30MPa, ultrafiltration time of 10min, ultrafiltration temperature of 40℃ and feeding concentration of 1.8mg/mL.The practical membrane flux was 0.070 mL/cm2?min,close to the predicted membrane flux of 0.077 mL/cm2?min.
