Abstract:

An oligosaccharide, α-D-Gal-(1→3)-α-D-Gal-(1→6)-α-D-Glc-(1→2)-β-D-Fru (BO-1), was isolated from the seed of Bixo orellana. The 13C  and 1H NMR chemical shifts of the compound were assigned by 1D and 2D NMR techniques, including COSY、HMQC and HMBC.

Key words: NMR,  Bixo orellana, oligosaccharide, chemical shift assignment
