Recently, thearticle entitled " Structural characterization of a sulfated galactofucanfrom Undaria pinnatifida and its effect on type 2 diabetic mice" by Mr. Ke Songze and Zhang Bo of our group was accepted bythe Journal of Oceanology and Limnology. In this article, the structuralfeature of Undaria pinnatifid galactofucan (UpG) was determined byGC-MS, FT-IR, NMR and LC-MS. Then, UpG showed anti-hyperglycemic, anti-hyperlipidemicand regulated gut microbiota activities in vivo. This work was completedunder the guidance of Prof. Wang Hong and Dr. Wei Bin.
