Chemical investigation of the roots of Wilbrandia ebracteata Cogn. (Cucurbitaceae) led to the isolation of two new (1- 2) and four known (3- 6) cucurbitacins. Their structures were elucidated by NMR and MS and compared with related compounds. The in vitro cytotoxicity of isolated compounds was evaluated against RD, KB, HCT-8, and A549 cell lines showing strong activity.
对Wilbrandia ebracteata Cogn.（葫芦科）的根进行化学研究，分离得到两种新的（1-2）和四种已知的（3-6）葫芦素。通过 NMR 和 MS 确定了它们的结构，并与相关化合物进行了比较。对分离得到的化合物进行了体外细胞毒性测试，结果显示对 RD、KB、HCT-8 和 A549 细胞系具有很强的活性。
