Abstract

Two new neo-clerodane type diterpenoids, teulolin A (15,16-epoxy- 6β,7β,18,19-tetrahydroxy-neo-cleroda-3(4),3(16),14-trien-20,12(S)-olide, 1) and teulolin B (15,16-epoxy-3α,6β,7β,18,19-tetrahydroxy-neo-cleroda- 4(18),13(16),14- trien-20,12(S)-olide, 2) were isolated from the aerial parts of Teucrium polium. The structures of 1-2 were proposed on the basis of extensive NMR experiments and molecular modeling studies.
