Abstract
Six new triterpene saponins and a new lignan have been isolated from the n-BuOH and EtOAc solubles of the MeOH extracts of the whole plant of Clinopodium urticifolium. The structures of the new secondary metabolites, named clinopodiside I-V (6, 1, 2, 3, 4), clinoposaponin Ga (5) and R-(Z)-rosmarinic acid B (7), were deduced from the spectroscopic data (1D, 2D-NMR, FAB-MS, HRESI-MS, EI-MS) and by chemical transformation studies.
