Abstract Three new neo-clerodanediterpenoids, teulepicin, 19-acetylteulepicin and teulepicephin, have been isolated, together with the previously known flavone cirsiliol from the aerial parts of Teucrium lepicephalum . The structures of the diterpenoids were established by chemical and spectroscopic means and by correlation with known substances. In addition, 19-acetylteulepicin and the already known
