| Abstract: | Sialyl oligosaccharides were separated from two samples of Japanese black bear milk by extraction with chloroform/methanol, gel filtration on Bio Gel P-2, ion exchange chromatography on DEAE-Sephadex A-50 and high-performance liquid chromatography (HPLC) on a TSK gel Amido-80 column. They were characterized by 1H-NMR spectroscopy. The structures of four sialyl oligosaccharides separated from the milk were the following:
