Wiedemanniosides A-E: new phenylethanoid glycosides from the roots of Verbascum wiedemannianum.
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 spectroscopic techniques (NMR, HR-ESIMS, IR, and UV).
