Objective:
To study the extraction technology of polysaccharide from Penthorum chinense.
Methods:
Single factor test and orthogonal experiment design methods L9 (3(3)) were applied to analyze the influence of solid-liquid rate, extraction temperature and time on the extraction percent of polysaccharide from Penthorum chinense.
Results:
The temperature significantly affected the extraction percent of the soluble polysaccharide, and the optimum conditions for the extraction technology were as follows: solid-liquid rate at 1:15, temperature at 95 degrees C, time for 3h. Under this condition, the extraction percent of polysaccharide from Penthorum chinense was 1.12%, RSD = 1.21%.
Conclusion:
The research can provide a theoretical foundation for further development and utilization of polysaccharide from Penthorum chinense.
