Abstract
Two new neo-clerodane type diterpenoids, teulolin A (15,16-epoxy-6 beta,7 b eta,18,19-tetrahydroxy-neo-cleroda-3(4),13(16),14-trien-20,12(S)-olide, 1) and teulolin B (15,16-epoxy-3 alpha, 6 beta, 7 beta, 18, 19-tetrahydroxy-ne o-cleroda-4(18),13(16),14-trien-20,12(S)-olide, 2) were isolated from the a erial parts of Teucrium polium. The structures of 1-2 were proposed on the basis of extensive NMR experiments and molecular modeling studies. (C) 1999 Elsevier Science Ltd. All rights reserved.
