- Abstract: OBJECTIVE: To characterize the chemical structure of a homogenous polysaccharide CTP3-E purified from Crepis turczaninowii C. A. Mey. METHODS: Sugar composition analysis, methylation analysis, IR and NMR (Dept, HMBC, HMQC, etc.) were used to elucidate the structure. RESULTS: The molecular weight of CTP3-E was 12182. CTP3-E was composed of mannose, rhamose, glucuronic acid, galacturonic acid, glucose, galactose, and arabinose. CONCLUSION: CTP3-E is a new acidic heteropolysaccharide and was isolated from this medicinal plant for the first time.
