Stevia Rebaudiana Studies

New Non-Glycosidic Diterpenes from the Leaves of Stevia rebaudiana 2003  [PDF]

Six new labdane-type, non-glycosidic diterpenes, sterebins I-N (1-6), were isolated from the leaves of Stevia rebaudiana. Their structures, analogous to those of the previously described sterebins A-H, were elucidated on the basis of spectroscopic and chemical studies.
