From the aerial parts of Verbascum wiedemannianum Fisch. & Mey. four new phenylethanoid glycosides (wiedemanniosides B-E) were isolated along with four known compounds; 6-O-acetylmartynoside ( = wiedemanniosides A), verbascoside, martynoside, echinacoside and leucosceptoside B. The structures of the new compounds were elucidated by employing spectro-scopic techniques (NMR, HR-ESIMS, IR, and UV).
