Two new sesquiterpenoids, named dalodorin A () and dalodorin B (), together with four known sesquiterpenoids, were isolated from the heartwood of . Their structures were elucidated on the basis of spectroscopic analysis including 1D and 2D NMR techniques and HR-ESI-MS. Evaluation of the isolated compounds for cytotoxicity against two human cancer cell lines (Hela and HepG-2) showed moderate activities (25.22-60.45 μM).
从[植物名称]的心材中分离出两种新的倍半萜类化合物，命名为达洛多灵A（）和达洛多灵B（），以及四种已知的倍半萜类化合物。基于包括一维和二维核磁共振技术以及高分辨电喷雾电离质谱在内的光谱分析阐明了它们的结构。对分离出的化合物针对两种人类癌细胞系（Hela和HepG - 2）的细胞毒性进行评估，结果显示具有中等活性（25.22 - 60.45 μM）。
