Notes:
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 13β, 28-epoxy-3-β-{{[β-D-glucopyranosyl-(1→2)]-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)]-β-D-fucopyranosyl}-oxy} olean-11-en-23-ol (1), 3-β-{{[β-D-glucopyranosyl-(1→2)]-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)]-β-D-fucopyranosyl}oxy}olena-11, 13(18)-diene-23, 28-diol (2), 3-β-{{[β-D-glucopyranosyl-(1→2)]-[α-L-rhamnopyranosyl-(1→4)-β-Dglucopyranosyl-(1→3)]-β-Dfucopyranosyl}oxy}-11α-methoxyolean- 12-ene-23, 28-diol (3), and 3-β-{{[β-D-glucopyransoyl-(1→2)]-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)]-β-D-fucopyranosyl}oxy}olean-12-ene-11α,23,28-triol(4).
