In this work, the detailed NMR studies and full 13 C NMR assignments for five diterpenoids isolated from Sideritis caesarea and Sideritis athoa are described. The assignments are based on a combination of 1D and 2D NMR techniques including 1 H, 13 C, 1 H 1 H COSY, gHSQC [ 1 J (C,H)] and gHMBCδ C [ n J (C,H) ( n = 2 and 3)] and NOESY experiments.
