Triterpene Saponins from the Fruits of Phytolacca rugosa (Phytolaccaceae)

2010

Four known serjanic acid glycosides were isolated from the fruits of Phytolacca rugosa and characterized mainly by 2D NMR spectroscopy and mass spectrometry. This aglycon has a chemotaxonomic significance for the genus Phytolacca.

Steroidal Saponins from the Fruits of Cestrum ruizteranianum

2011

Seven spirostane and furostane-type glycosides were isolated from the aqueous methanolic extract of the fruits of Cestrum ruizteranianum and characterized mainly by 2D NMR spectroscopy and mass spectrometry. These known saponins belong to the Δ5-spirostene and Δ5-furostene series and are reported in this species for the first time.
