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)-alpha-L-rhamnopyranosylaucubin (1), 6-O-(4"-O-traps-p-methoxycinnamoyl)-alpha-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.
