Phytochemical investigations on the above ground parts of Lamium garganicum subsp. laevigatum resulted in the isolation of seven iridoid glucosides, shanzhiside methyl ester (1), barlerin (8-O-acetylshanzhiside methyl ester; 2), 6-O-syringyl-8-O-acetylshanzhiside methyl ester (3), 6β-hydroxyipolamiide (4), lamalbide (5), dehydropenstemoside (6), and sesamoside (7). The structure of the iridoids was elucidated by spectroscopic (UV, IR, 1D- and 2D-NMR, and ESI-MS) evidence.
