Four undescribed butanolides, linderangolides A-D (1-4), along with four known congeners, lincomolide A (5), (-)-epilitsenolide C2 (6), (-)-epilitsenolide C1 (7) and litseakolide H (8), were isolated from the roots of Lindera angustifolia. The planar structures of 1-4 were elucidated based on extensive spectroscopic analyses, the relative and absolute configurations of 1-4 were determined by the NOESY spectra and the comparison of calculated and experimental ECD. The cytotoxic activities of all isolated compounds were tested, 4 showed inhibitory activity against SGC-7 cells with IC value of 6.62 μM.
从狭叶山胡椒的根中分离出了四种未描述的丁内酯，即乌药内酯A-D（1-4），以及四种已知的同系物，林可莫利德A（5）、（-）-表柳叶木兰内酯C2（6）、（-）-表柳叶木兰内酯C1（7）和乌药内酯H（8）。基于广泛的光谱分析阐明了1-4的平面结构，通过NOESY光谱以及计算和实验ECD的比较确定了1-4的相对和绝对构型。测试了所有分离化合物的细胞毒性活性，化合物4对SGC-7细胞显示出抑制活性，IC值为6.62 μM。
