Keywords Two known furanoid diterpenes Teucrin A (1) and Teucrin E (2) were isolated from the bitter fraction of the aerial parts of Teucrium chamaedrys L. Besides these two compounds, Teuchamaedryn A (3) and B (4) were isolated from the better fraction as well. The structure and the stereochemistry of Teuchamaedryn A, B and Teucrin E were established on the basis of spectral evidence, chemical transformation and correlation.
