Flavonol glycosides from Nitraria retusa.
The new flavonol trioside, isorhamnetin 3-O-4Rham-galactosylrobinobioside and five known flavonol glycosides, isorhamnetin 3-robinobioside, isorhamnetin 3-rutinoside, isorhamnetin 3-galactoside, isorhamnetin 3-glucoside and free isorhamnetin were isolated from the leaves and young stems of Nitraria retusa and characterized by UV and NMR spectroscopy. Isorhamnetin 3-xylosylrobinobioside was also tentatively identified.
