    • Labdane derivatives and alicyclic diterpenes from Gutierrezia espinosae 
      Zdero, C.; Bohlmann, F.; Niemeyer Marich, August (1990)
      The extract of the aerial parts of Gutierrezia espinosae gave 11 new and two known labdanes as well as five new nerylgeraniol derivatives. The structures were elucidated by high field 1H NMR spectroscopy. The chemotaxonomic ...
    • Labdane diterpenes from Haplopappus illinitus 
      Faini, Francesca; Labbé, C.; Torres, R.; Monache, G. D.; Monache, F. D. (2002)
      A chemical study of aerial parts of Haplopappus illinitus afforded five labdane diterpenoids whose structures were elucidated by high field NMR spectroscopy and 2D techniques. Four of them are dicarboxylic acids previously ...
