}The complete 1 H and 13 C NMR assignments for the diterpene glycoside 13-((2-O-β-D-xylopyranosyl-3-O- - D-glucopyranosyl-β-D-glucopyranosyl)oxy)-ent-kaur-16-en-19-oic acid β-D-glucopyranosyl ester (rebaudioside F) is o- lated from Stevia rebaudiana was achieved by the extensive 2D NMR (COSY, HSQC, HMBC) and mass spectral data. Further, hydrolysis of reba udioside F were performed using acid and enzymatic studies to identify their aglycone and sugar residues.
