Abstract

Four iridoid glucosides, aucubin1, ajugol2, ajugoside3, harpagoside4, and a phenylethanoid glycoside, verbascoside5 were isolated from the flowers of bioactive methanolic extract of Verbascum pycnostachyum Boiss & Helder. The structures of the compounds were determined from spectral methods UV, IR, 1D NMR and Mass Spec. . Ajugoside3 is encountered for the first time from Verbascum species.
