Five new oleanane saponins (1-5) together with 4 know flavonol glycosides were isolated from the aerial parts of S. erecta. Their structures were elucidated by 1D and 2D NMR expts. including 1D-TOCSY, DQF-COSY, ROESY, HSQC, and HMBC spectroscopy, as well as ESI-MS anal. The aglycon moieties of 1-4 were assigned as new oleanane derivs.
