Abstract
Three species of the genus Teucrium have been investigated. Two of the m (T. rivas-martinezii and T. divaricatum subsp. divaricatum) contain known neo-clerodane diterpenoids, and the other one (T. asiaticum) con tains a new neo-clerodane derivative, teucrasiatin, together with anot her previously known diterpene. The structure of teucrasiatin [(12S,20 S)-19-acetoxy-4 alpha,18;15,16-diepoxy-6-oxo-neo- cleroda-13(16),14-di ene-20,12-hemiacetal] was established by chemical and spectroscopic me ans.
