ABSTRACT
Objective To study the degradation of Rhizoma Typhonii polysaccharide with sulfuric acid under the normal and ultrasonic condition. Methods The orthogonal test table L9(34) was used to optimize 4 factors including acid concentration, reaction time, reaction temperature and ultrasonic power, with the yield of the low-molecular-weight polysaccharide as the index. Results The optimal conditions of discomposing Rhizoma Typhonii polysaccharide with sulfuric acid were 10% sulfuric acid, 100 ℃ for 2 h under the normal condition,and the yield of low-molecular-weight polysaccharide was 36.17%. Under the ultrasonic condition, the optimal conditions were 150 W of the ultrasonic power, 5% sulfuric acid, 40 ℃ for 1 h, and the yield was 44.63%. Conclusion The degrading yield of the low-molecular-weight polysaccharide can be increased under ultrasonic condition with sulfuric acid.
