| Abstract: | To investigate the optimal sulfation technology of exopolysaccharide from Poria cocos mycelia. Based on the single factor design, the sulfation technology of exopolysaccharide was optimized by the response surface methodology. The results showed that the optimal sulfa- tion technology of exopolysaccharide were as follows, chlorosulfonic acid and pyridine mole ratio of 1.3.85, reaction temperature 73 C and reaction time 3.34 h. Under those conditions, the de- gree of substitution was 1.02. |
