Neolignan and phenylethanoid glycosides from Verbascum salviifolium Boiss
From the aerial parts of Verbascum salviifolium Boiss., 2 neolignan glucosides, dehydrodiconiferyl alcohol-9'-O-beta-D-glucopyranoside (1) and dehydrodiconiferyl alcohol-9-O-beta-D-glucopyranoside (2), along with 5 phenylethanoid glycosides, acteoside (= verbascoside) (3), beta-hydroxyacteoside (4), forsythoside B (5), angoroside A (6) and martynoside (7), were isolated. The structure elucidation of the isolated compounds was established on the basis of spectroscopic evidence. Compounds 1-7 demonstrated scavenging properties toward the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical in TLC autographic and spectroscopic assays.
