Phytochemical reinvestigation of the dried roots and rhizomes of Helleborus thibetanus afforded four new minor spirostanol glycosides (1-4) and four known spirostanol glycosides (5-8). Their structures were determined on the basis of spectroscopic analyses, including 1D and 2D NMR experiments, together with HR-ESI-MS and IR measurements and the results of acid hydrolysis.
对太白铁线莲干燥根及根茎进行植物化学再研究，得到了4个新的微量螺旋甾烷醇苷（1 - 4）和4个已知的螺旋甾烷醇苷（5 - 8）。它们的结构是基于光谱分析确定的，包括一维和二维核磁共振实验，以及高分辨电喷雾电离质谱和红外测量，还有酸水解的结果。
