Chemical Constituents from <i>Clinopodium Urticifolium</i>

Abstract

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.
