Optimization of Ultrasonic Degradation Technology for Polysaccharides from Lycii Fructus by Orthogonal Test
Objective: To optimize ultrasonic degradation technology of polysaccharides from Lycii Fructus. Method: With small molecule polysaccharides from Lycii Fructus(LBP-s
the relative molecular mass<30 000)
based on single factor tests
orthogonal test was adopted to investigate effects of ultrasonic frequency
ultrasonic time and reaction temperature on ultrasonic degradation technology of LBP. Result: Optimum ultrasonic degradation technology conditions of LBP were as follows:ultrasonic frequency 40 kHz
ultrasonic time 1.5 h
reaction temperature 40℃
yield of LBP-s was up to 80.04%. Conclusion: Optimized degradation process of LBP was stable and feasible with good application prospect.
