Phytochemical investigation of the tubers of Ophiopogon japonicus led to the isolation of five previously undescribed steroidal saponins, ophiojaponins A-E, together with twelve known ones. The structures of these isolated compounds were elucidated by detailed spectroscopic analyses and chemical methods. Ophiojaponins A-C are rare naturally occurring C29 steroidal glycosides possessing a homo-cholestane
麦冬块茎的植物化学研究导致分离出五种以前未描述的甾体皂苷,即麦冬素 AE,以及十二种已知的皂苷。通过详细的光谱分析和化学方法阐明了这些分离化合物的结构。Ophiojaponins AC 是罕见的天然 C29 甾体糖苷,具有高胆固醇骨架和芳香环 E. Ruscogenin 1-O-α-L-rhamnopyranosyl-(1 → 2)-4-O-sulfo-β-D-fupyranosido- 3-O-β-D-吡喃葡萄糖苷作为单一成分被分离出来,并首次报道了其完整的光谱数据。评估了分离的甾体皂苷对两种人肿瘤细胞系 MG-63 和 SNU387 的细胞毒性。他们之中,
