Activation of a Sweet Taste Receptor by Oleanane-Type Glycosides from Wisteria sinensis

2022

The phytochemical study of Wisteria sinensis (Sims) DC. (Fabaceae), commonly known as the Chinese Wisteria, led to the isolation of seven oleanane-type glycosides from an aqueous-ethanolic extract of the roots. After successive purifications by various chromatographic methods, like solid/liquid chromatographic methods, vacuum liquid chromatography (VLC), medium pressure liquid chromatography (MPLC), on normal and reverse phase (RP-18 silica gel), and size exclusion chromatography on Sephadex L, their structures were elucidated by an extensive 600 MHz NMR analysis including 1D and 2D NMR experiments as well as ESI-MS. Among the seven isolated saponins, two have never been reported before : 3…

Triterpene Saponins from Wisteria floribunda “macrobotrys” and “rosea”

2017

Five oleanane-type saponins were isolated from two cultivars of Wisteria floribunda (Willd.) DC. (Fabaceae): From the roots of Wisteria floribunda “macrobotrys”, one new oleanane derivative elucidated as 3- O-β-D-xylopyranosyl-(1→2)-β-D-glucuronopyranosyl-22- O-acetyl-3p,22p,24-trihydroxyolean-12-en-30-oic acid, and two known glycosides, and from the roots of Wisteria floribunda “rosea”, two known ones. Their structures were elucidated by a detailed 600 MHz NMR analysis including 1D and 2D NMR (1H, 13C, COSY, TOCSY, ROESY, HSQC, HMBC) experiments and mass spectrometry. Chemotaxonomic conclusions were proposed.
