In this work we investigated mixtures from α-glycosylation of rubusoside with cyclodextrin glycosyltransferases. In addition to the previously known α-1,4 glycosylated derivatives, nine new compounds with rare α-1,3-glycosidic bonds were identified based on nuclear magnetic resonance spectroscopy and mass spectrometric analysis. Furthermore, sensory properties of monoglycosylated rubusoside derivatives were investigated and compared to previously described monoglycosylated compounds. Additionally, digestion with α-amylase from human saliva was investigated for different glycosylated rubusoside derivatives.
在这项工作中，我们研究了毛蕊花糖苷与环糊精糖基转移酶的 α-糖苷化混合物。除了先前已知的α-1,4 糖苷化衍生物外，基于核磁共振波谱和质谱分析，还鉴定了九种具有罕见α-1,3-糖苷键的新型化合物。此外，还研究了单糖苷化毛蕊花糖苷衍生物的感官特性，并与先前描述的单糖苷化化合物进行了比较。此外，还研究了不同糖苷化毛蕊花糖苷衍生物与人唾液中的α-淀粉酶的消化情况。
