A new furospirostanol saponin, ophiofurospiside A (1), was isolated together with the known steroidal glycosides 2, 3, and 4 from the tubers of Ophiopogon japonicus (Thunb.) Ker-Gawl. Using chemical and spectral analyses (IR, MS, 1D NMR, and 2D NMR), the structure of 1 was established as 26-O-beta-d-glucopyranosyl-(22S, 25R)-furospirost-5-ene-3beta, 17alpha, 26-triol-3-O-[alpha-l-rhamnopyranosyl-(1 --> 2)]-[beta-d-xylopyranosyl-(1 --> 4)]-glucopyranoside (1). Three known steroidal saponins 2-4 were identified on the basis of spectroscopic data.
从麦冬（Ophiopogon japonicus (Thunb.) Ker-Gawl.）块茎中分离出一种新的呋甾螺烷醇皂苷——麦冬呋螺皂苷A（1），以及已知的甾体糖苷2、3和4。通过化学和光谱分析（红外光谱、质谱、一维核磁共振和二维核磁共振），确定1的结构为26-O-β-D-吡喃葡萄糖基-(22S, 25R)-呋螺甾-5-烯-3β, 17α, 26-三醇-3-O-[α-L-鼠李吡喃糖基-(1→2)]-[β-D-木吡喃糖基-(1→4)]-吡喃葡萄糖苷（1）。根据光谱数据鉴定出三种已知的甾体皂苷2-4。
