In this work, the detailed NMR studies and full (13)C NMR assignments for five diterpenoids isolated from Sideritis caesarea and Sideritis athoa are described. The assignments are based on a combination of 1D and 2D NMR techniques including (1)H, (13)C, (1)H-(1)H COSY, gHSQC [(1)J(C,H)] and gHMBCδ(C) [(n)J(C,H)(n=2 and 3)] and NOESY experiments.
本工作对采自长管兔耳草(Sideritis caesarea)和阿氏兔耳草(Sideritis athoa)的五种二萜类化合物进行了详细的 NMR 研究和全(13)C NMR 赋值。这些赋值是基于 1D 和 2D NMR 技术的组合，包括(1)H、(13)C、(1)H-(1)H COSY、gHSQC[(1)J(C,H)]和 gHMBCδ(C)[(n)J(C,H)(n=2 和 3)]以及 NOESY 实验。
