[Extraction of polysaccharide from Penthorum chinense].
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%.


CONCLUSIONS
The research can provide a theoretical foundation for further development and utilization of polysaccharide from Penthorum chinense.
