Four new steroidal saponins, filiasparosides A-D (1-4), together with known aspafiliosides A (5) and B (6) were isolated from the roots of Asparagus filicinus. The structures of these new compounds were elucidated by detailed spectroscopic study and chemical analysis. Compounds 1-6 were cytotoxic against human lung carcinoma (A549) and breast adenocarcinoma (MCF-7) tumor cell lines with EC(50) values of 2.3-16.8 microg/mL. Compound 3 showed the most potent cytotoxicity, with EC(50) values of 2.3 and 3.0 microg/mL toward A549 and MCF-7 cell lines, respectively.
从天门冬的根部分离出了四种新的甾体皂苷,即天门冬皂苷A-D(1-4),以及已知的天门冬皂苷A(5)和B(6)。通过详细的光谱研究和化学分析阐明了这些新化合物的结构。化合物1-6对人肺癌(A549)和乳腺腺癌(MCF-7)肿瘤细胞系具有细胞毒性,其半数有效浓度(EC50)值为2.3-16.8微克/毫升。化合物3表现出最强的细胞毒性,对A549和MCF-7细胞系的EC50值分别为2.3和3.0微克/毫升。
