Abstract
five neo-clerodane diterpenes were isolated from the aerial parts of Teucrium polium ssp. aurasianum. One was known (teumicropodine) and the others were new 3-deacetylteumicropodine,3,20-bis-deacetylteupyreinidine, 6,20-bis-deacetylteupyreinidine and 3,6,20-tri-deacetylteupyreinidine. Their structures and absolute stereochemistry were elucidated by spectral and correlation techniques.
