摘要：

With our interest of new diterpene glycosides with better taste profile than Rebaudioside M, we isolated and characterized two steviol glycosides with three additional glucose attached at the C-13 of Rebaudioside M or Rebaudioside D from an extract of Stevia rebaudiana Bertoni. Here we report the complete structure elucidations of diterpene glycosides on the basis of NMR experiments (H-1, C-13, COSY, HSQC-DEPT, HMBC, ID TOCSY, NOESY) and mass spectral data. Steviol glycosides that possess eight or nine glucose units are rarely reported in literature and could have an impact on the natural sweetener catalog.
