摘要

Glycosides, steviolside, and rubaudioside A, which are extracted from the leaves of Stevia rebaudiana, can be used as sweetener for food additive. Intermediates of steviolbioside, steviol, and isosteviol are very stable compounds obtained from benzotriazol-1-yloxtri(pyrrolidinol)phosphonium hexafluorophosphate. They are suitable to be used in amide and amide dimer synthesis. These nature product intermediates possess special characteristics. The spectra data showed two tautomeric groups: an ester form and an amide form. Their nuclear magnetic resonance, mass and chromatographic/mass/mass spectra were examined.
