Polyporus umbellatus
Key points
- OBJECTIVE: To prepare and sulfate of polysaccharide from Polyporus umbellatus, and to compare the results of joined dispersant or not
- METHODS: After purified, SEC-LLS was used to determine the molecular weight of polysaccharide
- RESULTS: The results showed that the distribute of molecular weight was narrow
- It was a water-soluble glycosaminoglycan with a molecular weight of nearly 1. 6 x 10(5) Del
- CONCLUSION: A kind of beta-D-glucopyranoside was obtained with a molecular weight of nearly 1. 6 x 10(5) Del
- After added dispersant, the production of sulfated polysaccharide increased, but the molecular weigh and the content of sulfate group was reduced

OBJECTIVE: To prepare and sulfate of polysaccharide from Polyporus umbellatus, and to compare the results of joined dispersant or not.
METHODS: After purified, SEC-LLS was used to determine the molecular weight of polysaccharide. The polysaccharide was sulfated with the method of chlorosulfonic acid pyridine. The structures of polysaccharide and sulfated polysaccharides was determinated by FI RD analyse.
RESULTS: The results showed that the distribute of molecular weight was narrow. It was a water-soluble glycosaminoglycan with a molecular weight of nearly 1. 6 x 10(5) Del. And sulfated polysaccharide was received by sulfation.
CONCLUSION: A kind of beta-D-glucopyranoside was obtained with a molecular weight of nearly 1. 6 x 10(5) Del. After added dispersant, the production of sulfated polysaccharide increased, but the molecular weigh and the content of sulfate group was reduced.
