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.
从荆条（Teucrium chamaedrys（L.））的有机提取物中分离得到三种新的去甲新克列烷二萜，分别命名为 chamaedryoside A（1）、B（2）和 C（3）。通过（1）H 和（13）C-NMR 谱、DEPT、COSY、TOCSY、HSQC、HSQC-TOSCY 和 HMBC 实验以及 ESI-MS/MS 技术对其结构进行了表征。通过 NOESY 和计算计算阐明了立体结构。
