Abstract:

It has been reported that the polysaccharide is the main active constituent of Hericium erinaceur. A series of oligosaccharide(mixtures of disaccharide and heptasaccharide of Hericium erinaceur) were separated from Hericium erinaceur by empty-fibrin filtration. Disaccharide and trisaccharide were purified via HPLC with NH2 column. Component sugars and glycosidic linkage ways were analysed via GC and GC-MS. Electrospray ionization tandem mass spectrometry(MSn) was used for the oligosaccharides structure study and the result shows that the disaccharide has two kind of structural styles and trisaccharide has one kind of structural style.

Key words: Hericium erinaceur, Oligosaccharide, Electrospray ionization tandem mass spectrometry
