Three new steroidal saponins, Vernoniosides S1 (1), Vernoniosides S2 (2) and Vernoniosides S3 (3) were isolated from the stem of Vernonia cumingian. Their chemical structures were elucidated on the basis of MS, NMR spectroscopic and chemical analysis. Complete assignment of (1)H and (13)C NMR spectroscopic data were achieved by 1D and 2D NMR experiments (HMQC, HMBC, ROESY).
从库氏斑鸠菊的茎中分离出了三种新的甾体皂苷，即斑鸠菊苷S1（1）、斑鸠菊苷S2（2）和斑鸠菊苷S3（3）。基于质谱、核磁共振光谱和化学分析对它们的化学结构进行了阐明。通过一维和二维核磁共振实验（HMQC、HMBC、ROESY）完成了对1H和13C核磁共振光谱数据的全归属。
