Ilwensisaponin C (= 3-O-{[α-L-rhamnosyl-(1→4)-(β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl]- (1→2)-β-D-fucopyranosyl}-11-methoxy-olean-12-ene-3β, 23, 28-triol) (1), ilwensisaponin A (= mimengoside A = 3-O-{[α-L-rhamnosyl-(1→4)-(β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl]-(1→2)-β-Dfucop- yranosyl}-13β, 28-epoxyolean-11-ene-3β, 23-diol) (2), ajugol (3), picroside IV (= 60 -O-trans-phydroxycin- namoylcatalpol) (4), verbascoside {= acteoside, [β-(3,4-dihydroxyphenyl)-ethyl]-(30 -O-α-Lrhamnopyra- nosyl)-(40 -O-caffeoyl)-β-D-glucopyranoside} (5) and 1-(β-D-glucopyranosyl)-8-hydroxy-3, 7-dimethyl-oct-2(E), 6(E)- dienoate (6) were isolated from the flowers of Verbascum pterocalycinum var. mutense Hub.-Mor. The structures of the compounds were determined primarily from 1D and 2D NMR experiments. This is the first phytochemical study performed on V . pterocalycinum var. mutense and the first report of the presence of 1-(β-D-glucopyranosyl)-8-hydroxy-3, 7-dimethyl-oct-2(E), 6(E)- dienoate (5) as a monoterpene glycoside along with picroside IV (= 60 -O-trans-p-hydroxycinnamoylcatalpol) (4) from the genus Verbascum.
