The aerial parts of Verbascum sinaiticum Benth. (Scrophulariaceae) yielded two iridoids that were idenified as ajugol 3 and aucubin 4. Also, investigation of the flavonoid constituents revealed the isolation and identification of luteolin 1 and chrysoeriol-7-glucoside 2. All the isolated compounds were identifid by spectroscopicmethods (UV, MS, $^{1}H-NMR$ and $^{13}C-NMR$) and in comparison with the literature data. Both alcohol and methylene chloride/methanol extracts (1 : 1) exhibited a hepatoprotective effect by $CCl_{4}challenge$ test.
