Abstract: Reductive cleavage of the riboflavin-binding glycoprotein from hen egg white with LiBH4/tert-BuOH followed by NaBH4 treatment gave rise to oligosaccharide alditols. After fractionation by HPLC two individual oligosaccharide alditols of a hybrid type were isolated. Their structures were proved by 1H NMR 500 MHz spectroscopy and methylation analysis. One of the oligosaccharides has earlier been found in ovalbumin, whereas the other is identified in glycoproteins for the first time.
