Studies on Carbohydrates Ⅱ.The FABMS of Glycosyl Cinnamoates Carbohydrate Esters

Fourteen 1-O-cinnamoyl-β-D-glucopyranose tetraacetate and its analogs were determined by fast atom bombardment (FAB) ionizastion technique. The FABMS demonstrated very clear protonated molecular ion in molecular ion area. In this paper the main fragmentation were discussed in comparasion with the EIMS. The FABMS of these compounds have not appeared in the literature before.
