Özet
From the aerial parts of the plant Verbascum salviifolium, two new iridoid glucosides, 6-O-ß-D-glucopyranosylcatalpol (1) and 6-O-(6¨-O-trans-p- hydroxycinnamoyl)-ß-D-glucopyranosylaucubin (2) along with five known iridoid glycosides, 6-O-ß-D-glucopyranosylaucubin (3), 6-O-?-L- rhamnopyranosylcatalpol (4), verbaspinoside [= 6-O-(2¨-O-trans-cinnamoyl)- ?-L-rnamnopyranosylcatalpol] (5), pulverulentoside I [= 6-O-(2¨-O-trans-p-methoxycinnamoyl-3¨-O-acetyl)-?-L- rhamnopyranosylcatalpol] (6), and buddlejoside A8 [= 6-O-(4¨-O-trans-3,4-dimethoxycinnamoyl)-?-L-rhamnopyranosylcatalpol] (7) were isolated. The structures of the new compounds were established on the basis of spectroscopic evidence.
