Abstract
On further phytochemical investigation of the aerial parts of Verbascum undulatum, two new acylated iridoid glycosides, 6-O-[3-O-(trans-3,4-dim ethoxycinnamoyl)-α- ʟ-rhamnopyranosyl] aucubin (1) and 6-O -[3-O-(trans-p-methoxycinnamoyl)-α-ʟ-rhamnopyranosyl]aucubin (2) were isolated. These structures were determined by spectral methods, mainly by 1D and 2D NMR spectroscopy.
