Abstract

Three new nor-neo-clerodane diterpenes, named chamaedryoside A (1), B (2) and C (3), have been isolated from the organic extracts of Teucrium chamaedrys (L.) and their structural characterization has been accomplished by (1)H and (13)C-NMR spectra, and DEPT, by COSY, TOCSY, HSQC, HSQC-TOSCY and HMBC experiments, as well as by ESI-MS/MS techniques. The stereostructures have been elucidated by NOESY and computational calculations. 2009 John Wiley & Sons, Ltd.
