Two new (1-2) and five known iridoid glycosides (3-7) as well as a known saponin (8) were isolated from the flowers of Verbascum lasianthum and their structures were determined as 6-O-(4″-O-trans-p-coumaroyl)-α-L- rhamnopyranosylaucubin (1), 6-O-(4″-O-trans-p-methoxycin-namoyl)-α- L-rhamnopyranosylaucubin (2), sinuatol (3), aucubin (4), geniposidic acid (5), catalpol (6), ajugol (7) and ilwensisaponin A (8) on the basis of 1D and 2D NMR spectral analysis. © 2006 Verlag der Zeitschrift für Naturforschung.
