13C nmr study of α- and β-anomeric pairs of d-mannopyranosides and l-rhamnopyranosides
TL;DR: The results obtained in this paper are valuable for the structure studies of plant-glycosides as well as carbohydrates, especially for determination of anomeric configurations of mannosides and rhamnosides which has been extremely difficult by other classical techniques.
Journal ArticleDOI
New sweet diterpene glucosides from Stevia rebaudiana
TL;DR: In this paper, two new glucosides, rebaudiosides A and B, were isolated from the leaves of Stevia rebaudiana and formulated as β-glucosyl ester.

Journal ArticleDOI
Steroidal saponins from fruits of Tribulus terrestris
TL;DR: The structures of the new saponins were elucidated on the basis of spectroscopic analyses, including two-dimensional NMR techniques, and chemical reactions.
