糖类研究Ⅱ.桂皮酸类糖酯的FABMS研究

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

摘要: 本文报道使用快原子轰击技术测定14个桂皮酸类化合物糖酯的质谱,均获得明显的准分子离子(M+H)~+。本文还对这类化合物的FABMS的裂解方式进行讨论,并与EIMS进行比较。这类化合物的FABMS与大多数的EIMS在文献中尚未见报道。

Abstract: 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.
