It is well known that spirostane-type saponins show various bioactivities. In our on-going program of screening these kinds of constituents from natural products, was found to be rich in them, and nine new spirostanol saponins, Yucca spirostanosides A₁ (), A₂ (), B₁ (), B₂ (), B₃ (), C₁ (), C₂ (), C₃ (), and D₁ (), together with five known ones (-) were isolated from the plant. Their structures were elucidated by extensive spectroscopic methods, including 1D and 2D NMR and MS spectra, and comparing with published data.
众所周知，螺甾烷型皂苷具有多种生物活性。在我们正在进行的从天然产物中筛选这类成分的计划中，发现富含此类成分，从该植物中分离得到了 9 种新的螺甾烷醇皂苷，分别为 Yucca spirostanosides A₁ ()、A₂ ()、B₁ ()、B₂ ()、B₃ ()、C₁ ()、C₂ ()、C₃ ()和 D₁ ()，以及 5 种已知的 (-)。通过包括 1D 和 2D NMR 和 MS 光谱在内的广泛光谱方法，并与已发表的数据进行比较，阐明了它们的结构。
