The structures of the compounds were determined primarily from 1D and 2D NMR experiments. This is the first phytochemical study performed on V. pterocalycinum var. mutense and the first report of the presence of 1-insert ignore into journalissuearticles values(b -D-glucopyranosyl);-8-hydroxy-3, 7-dimethyl-oct-2insert ignore into journalissuearticles values(E);, 6insert ignore into journalissuearticles values(E);- dienoate insert ignore into journalissuearticles values(5); as a monoterpene glycoside along with picroside IV insert ignore into journalissuearticles values(= 6^{\prime}-O-trans-p-hydroxycinnamoylcatalpol); insert ignore into journalissuearticles values(4); from the genus Verbascum.
