A reductive LiBH4–But OH cleavage of N-glycosylamide carbohydrate–peptide bond allowed splitting off of oligosaccharide chains of the fucolectin, the bark agglutinin from the shrub golden rain Laburnum anagyroides (LABA). Four N-glycans were isolated by HPLC, and their structures were elucidated by monosaccharide analysis and 1 H NMR (500 MHz) spectroscopy: Man2Fuc1Xyl1GlcNAc2 (M2FX), Man3Xyl1GlcNAc2 (M3X), Man3Fuc1Xyl1GlcNAc2 (M3FX), and Man3Xyl1Fuc1GlcNAc3 (NM3FX). All the N-glycans contain D-xylose and three of them, L-fucose; they were found to be in a 1 : 8 : 3 : 1 ratio.
