Three new pterocarpans, named velucarpins A-C (1-3), along with three known pterocarpans (4-6) were isolated from the roots of Dalbergia velutina. Their structures were determined by spectroscopic analysis. All isolated compounds were evaluated for their cytotoxicity against KB and HeLa cell lines. Compounds 3 and 5 showed good cytotoxicity against KB and HeLa cells with IC50 values of 8.22, 8.09 μM and 5.99, 8.69 μM, respectively.
从绒毛黄檀根部分离得到三个新的紫檀烷类化合物，命名为绒毛紫檀素A - C（1 - 3），以及三个已知的紫檀烷类化合物（4 - 6）。通过光谱分析确定了它们的结构。对所有分离得到的化合物进行了针对KB和HeLa细胞系的细胞毒性评估。化合物3和5对KB和HeLa细胞显示出良好的细胞毒性，IC50值分别为8.22、8.09 μM和5.99、8.69 μM。
