New non-glycosidic diterpenes from the leaves of Stevia rebaudiana.
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.
