Two new oleanane saponins(1 and 2)and one new flavonol glycoside(3) together with six known flavonoids, were isolated from the aerial parts of Paronychia argentea. Their structures were elucidated by 1 D and 2D NMR experiments including 1D-TOCSY, DQF-COSY, NOESY, HSQC, and HMBC spectroscopy, as well as ESI-MS analysis. Copyright (C) 2007 John Wiley & Sons, Ltd.
