seven known oleanane-type triterpene saponins (3–9) were isolated from the leaves of Aralia armata. Their structures were determined by combination of HR-ESI-MS, 1 D and 2 D NMR spectral data as well as comparison with the previous literature. Compounds 6–9 exhibited cytotoxic effects towards three human cancer cell lines (HT29, A2058, and A549) with IC50 values ranging from 2.01 ± 0.17 to 18.8 ± 1.17 µM
摘要 两个新的,aramatosides A和B(1和2),用七已知齐墩果烷型三萜皂甙(一起3 - 9)从叶中分离龙牙ARMATA。它们的结构是通过结合 HR-ESI-MS、1 D 和 2 D NMR 光谱数据以及与以前的文献进行比较来确定的。化合物6 – 9对三种人类癌细胞系(HT29、A2058 和 A549)表现出细胞毒性作用,IC 50值范围为 2.01 ± 0.17 至 18.8 ± 1.17 µM。特别是,化合物7(水仙花素)对 HT29 和 A549 细胞系显示出显着的细胞毒活性,IC 50值分别为 2.02 ± 1.65 和 2.01 ± 0.17 µM,小于阳性对照盐酸伊立替康(IC 50值为 10.3 ± 1.32 和 9.89 ± 0.19 µM)。
