Polysaccharide from Gracilaria Lemaneiformis prevents colitis in Balb/c mice via enhancing intestinal barrier function and attenuating intestinal inflammation

This study explored the preventive effects of polysaccharide extracted from Gracilaria Lemaneiformis in mice with colitis induced by dextran sulfate sodium (DSS). FT-IR spectrum showed that SP was a typical sulfated polysaccharide (SP), which contained high content of S element in energy dispersive spectrometer (EDS) analysis. SP was mainly composed of (1 → 3)-linked glycosidic bonds. Our results showed that SP could improve physical conditions...
