Five neo-clerodane diterpenes were isolated from the aerial parts of T
eucrium polium ssp. aurasianum, One was known (teumicropodine) and the
others were new: 3-deacetylteumicropodine, 3,20-bis-deacetylteupyrein
idine, 6,20-bis-deacetylteupyreinidine and 3,6,20-tri-deacetylteupyrei
nidine. Their structures and absolute stereochemistry were elucidated
by spectral and correlation techniques.
