Two new iridoid glycosides, karsoside [1] and scropolioside D [2], were isolated from the aerial parts of Scrophularia ilwensis. Their structures were elucidated on the basis of chemical and spectral data as 6'-O-(beta-D-xylopyranosyl)-methylcatalpol and 6-O-[(2",4"-di-O-acetyl-3"-O-trans-cinnamoyl)-alpha-L-rhamnopyranosyl]- catalpol, respectively. Additionally, four known iridoids (aucubin, harpagide, 8-O-acetylharpagide, and ajugol), a phenylpropanoid glycoside (angoroside C), and two flavonoids (quercetin-3-O-rutinoside and kaempferol-3-O-rutinoside) were isolated and identified.
