Research Abstract |
Commercially available chondroitin sulfate was depolymerized by photolytic degradation system using titanium dioxide under 370~430 nm, and each oligosaccharide has been isolated and characterized by chromatographic and instrumentational techniques. Additionally, the purified chondroitin sulfate oligosaccharides were chemically over sulfonated using sulfur trioxide-pyridine complex and supplied for establishment of chondroitin sulfate oligomer library. Furthermore, these oligosaccharides were applied for the investigation of immune stimulating effects of chondroitin sulfate administered orally and found the exact size of oligosaccharide which is able to be absorbed through digestive system of mice.
