New Clerodane Derivatives from Teucrium scordium.
A reinvestigation of the aerial parts of TEUCRIUM SCORDIUM afforded in addition to several known diterpenes five new clerodane derivatives, all closely related to teucrin. The structures and the stereochemistry were elucidated by high resolution (1)H-NMR spectroscopy.
