Five new cholestane glycosides, named parisfargosides A-E (1-5), were isolated from the rhizomes of Paris fargesii. Their structures were elucidated on the basis of UV, HR-ESI-MS, 1D and 2D NMR data as well as chemical methods. The structures of all compounds contained α, β-unsaturated ketone unit. Compounds 3-5 possessed a 16,23-cyclocholest skeleton with 6/6/6/5/5 condensed ring, and the absolute configurations of C-16 and C-23 were confirmed according to ROESY spectra with pyridine‑d and DMSO‑d as solvents. In addition, the platelet aggregation activity and cytotoxic activity against five human cancer cell lines (HL-60, A549, SMMC-7721, MDA-MB-231, and SW480) of compounds 1-5 were evaluated.
从武当贝母的根茎中分离得到了五个新的胆甾烷糖苷，命名为巴黎 fargosides A-E（1-5）。基于 UV、HR-ESI-MS、1D 和 2D NMR 数据以及化学方法阐明了它们的结构。所有化合物的结构都含有α，β-不饱和酮单元。化合物 3-5 具有 16,23-环胆甾骨架和 6/6/6/5/5 稠合环，根据吡啶-d 和 DMSO-d 作为溶剂的 ROESY 谱确定了 C-16 和 C-23 的绝对构型。此外，还评估了化合物 1-5 对五种人癌细胞系（HL-60、A549、SMMC-7721、MDA-MB-231 和 SW480）的血小板聚集活性和细胞毒性活性。
