Eight undescribed triterpenoid saponins, scabiostellatosides A-H, together with three known compounds were isolated from the whole plant of Scabiosa stellata L. Their structures were established by spectroscopic analyses (1D, 2D-NMR and HRESIMS) and chemical methods. Scabiostellatosides A-H were evaluated for their cytotoxicity against human fibrosarcoma cell line (HT1080). Scabiostellatoside F, a heptasaccharide derivative of oleanolic acid, exhibited moderate cytotoxicity against HT1080 cell line with IC50 value of 12.0 μM.

阿尔及利亚东北部采集的星芒草中的三萜皂苷

八种未描述的三萜皂苷、scabiostellatosides AH 以及三种已知化合物从 Scabiosa stellata L 的全株中分离出来。它们的结构是通过光谱分析（1D、2D-NMR 和 HRESIMS）和化学方法确定的。评估了 Scabiostellatosides AH 对人纤维肉瘤细胞系 (HT1080) 的细胞毒性。Scabiostellatoside F 是齐墩果酸的七糖衍生物，对 HT1080 细胞系表现出中等的细胞毒性，IC50 值为 12.0 μM。
