Structure of neutral oligosaccharides from the enzyme hydrolysate of polysaccharide of peach gum (Prunus persica (L.) BATSCH)

Structures of two neutral oligosaccharides from the enzyme hydrolysate of the polysaccharide of peach gum were determined by mass spectrometry and gas chromatography. Tetrasaccharide III was proved to be O-β-D-galactopyranosyl-(1 → 6)-O-β-D-galactopyranosyl-(1 → 3)-O-β-D-galactopyranosyl-(1 → 6)-D-galactose and the disaccharide IV 3-O-α-D-mannopyranosyl-D-galactose.
