Abstract Four neo-clerodane diterpenoids, the new polivincins A – C and the known teulamifin B, were isolated by the phytochemical investigation of the acetone extract prepared from the aerial parts of Teucrium polium subsp. vincentinum, (Lamiaceae). The structure and stereochemistry of the compounds were established by IR, HRMS and different ( Al-Khalil, 1995 ) NMR and 2D-NMR techniques.
