Four new lindenane sesquiterpenoid dimers, spicachlorantins G-J (1-4), were isolated from the roots of Chloranthus spicatus together with seven known compounds, including chloramultilide A, shizukaol B, shizukaol D, shizukaol F, shizukaol P, chlorahololide D, and cycloshizukaol A. The planar structures of the new compounds were established by 1D-, 2D-NMR, and MS analyses. The absolute configurations of these compounds were determined by analyzing rotating Overhauser enhancement and exchange spectroscopy (ROESY) and circular dichroism (CD) spectra.
从宽叶金粟兰的根部分离得到了4个新的椴烷倍半萜二聚体，穗花氯安亭G-J（1-4），以及7个已知化合物，包括氯多内酯A、静香醇B、静香醇D、静香醇F、静香醇P、氯醇内酯D和环静香醇A。通过一维、二维核磁共振和质谱分析确定了新化合物的平面结构。通过分析旋转奥弗豪泽效应增强和交换光谱（ROESY）以及圆二色性（CD）光谱确定了这些化合物的绝对构型。
