Three new steroidal saponins (-), together with four known compounds (-), were isolated from the roots and rhizomes of Baker, and their structures were determined as (24, 25 )-1-hydroxy-3-[(-D-glucopyranoside)oxy]-spirost-5-en-24-yl--D-glucopyranoside () and (24S)-spirost-25(27)-en-1, 3, 4, 5, 6, 24-hexahydroxy-24---D-glucopyranoside (), (22, 25S)1, 3, 4, 5, 26, 27-hexanol-furospirost-5, 26---D-glucopyranoside (), together with four known compounds 3-epi-diosgenin-3--D-glucopyranosid (), 3-epiruscogenin (), 25(R)-1-hydroxy-spirost-5-en-3-yl---D-glucopyranoside () and tupichinin A (), on the basis of physico-chemical properties and spectral analysis. In this study, compounds - and - were evaluated for their cytotoxic activity against SW620, A549 and HepG2 tumor cell lines. Among them, compound showed moderate cytotoxicity against two human cancer cell lines A549 and HepG 2 with IC values of 25.3 ± 2.6 and 26.1 ± 2.5 μM, respectively.
从 Baker 的根和根茎中分离得到三个新的甾体皂苷（-），以及四个已知化合物（-），并鉴定了它们的结构为（24,25）-1-羟基-3-[-（-D-吡喃葡萄糖苷）氧基]-螺甾-5-烯-24-yl--D-吡喃葡萄糖苷（）和（24S）-螺甾-25（27）-烯-1,3,4,5,6,24-六羟基-24---D-吡喃葡萄糖苷（），（22,25S）1,3,4,5,26,27-六醇-呋喃螺甾-5,26---D-吡喃葡萄糖苷（），与四个已知化合物 3-表-薯蓣皂苷元-3--D-吡喃葡萄糖苷（），3-鲁斯可皂苷元（），25（R）-1-羟基-螺甾-5-烯-3-yl---D-吡喃葡萄糖苷（）和 tupichinin A（），基于物理化学性质和光谱分析。在这项研究中，对化合物 - 和 - 进行了细胞毒性活性评价，针对 SW620、A549 和 HepG2 肿瘤细胞系。其中，化合物 对两种人癌细胞系 A549 和 HepG2 显示出中等的细胞毒性，IC 值分别为 25.3±2.6 和 26.1±2.5 μM。
