Two new furostanol saponins, together with two known steroidal saponins, were isolated from the seeds of Trigonella foenum-graecum L. The structures of the new compounds were determined by detailed analysis of 1D NMR, 2D NMR, MS spectra and chemical evidences as 26-O-β-d-glucopyranosyl-(25S)-5-en-furost-3β,22α,26-triol 3-O-α-l-rhamnopyranosyl-(1 → 2)-[β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranosyl-
从龙骨草种子中分离了两种新的呋喃甾醇皂苷和两种已知的甾体皂苷。通过详细分析1D NMR,2D NMR,MS光谱和化学证据(如26- ø -β- d -glucopyranosyl-(25小号)-5-烯furost-3β,22α,26-三醇-3- ö -α-升-rhamnopyranosyl-(1→2) - [β- d -glucopyranosyl-( 1→6)-β- d -glucopyranosyl-(1→3)-β- d -glucopyranosyl-(1→4)] - β- d吡喃葡萄糖苷(1)和26- ö -β- d -glucopyranosyl-( 25 R)-5-烯furost-3β,22α,26-三醇-3- ö -α-升-rhamnopyranosyl-(1→2) - [β- d -glucopyranosyl-(1→6)] - β- d吡喃葡萄糖基-(1→3)-β- d-吡喃葡萄糖基-(1→
