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 1D and 2D NMR experiments including 1D‐TOCSY, DQF‐COSY, NOESY, HSQC, and HMBC spectroscopy, as well as ESI‐MS analysis. Copyright © 2007 John Wiley & Sons, Ltd.
