Abstract

From the aerial parts of Scrophularia ilwensis, four new triterpene saponins, ilwensisaponins A-D (1-4) were isolated. The structures of the compounds were elucidated using chemical and spectral data as 13beta,28-epoxy-3-beta {{[beta-D-glucopyranosyl-(1 --> 2)]-[alpha-L-rhamnopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 3)]-beta-D-fucopyranosyl}oxy}olean-11-en-23-ol (1), 3-beta-{{[beta-D-glucopyranosyl-(1 --> 2)]-[alpha-L-rhamnopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 3)]-beta-D-fucopyranosyl}oxy}oleana-11,13(18)-diene-23,28-diol (2), 3-beta-{{[beta-D-glucopyranosyl-(1 --> 2)]-[alpha-L-rhamnopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 3)]-beta-D-fucopyranosyl}oxy}-11alpha-methoxyolean-12-ene-23,28-diol (3), and 3-beta-{{[beta-D-glucopyranosyl-(1 --> 2)]-[alpha-L-rhamnopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 3)]-beta-D-fucopyranosyl}oxy}olean-12-ene-11alpha,23,28-triol (4).
