中文摘要：

运用硅胶、SephadexLH-20、0DD以及高效液相色谱法，从九子参的根中分离得到一个新三萜皂苷和一个已知三萜皂苷。通过质谱以及一维二维核磁确定了化合物的结构。化合物1和2均为首次从该属植物中分离得到。

英文摘要：

A new triterpenoid saponin （compound 1）, together with a known one （compound 2） was isolated from the roots of Silene rubicunda Franch. The isolation and purification were performed by a series of chromatographic techniques including silica gel, sephadex LH-20, and reversed-phase HPLC. Their structures were elucidated on the basis of combination of mass spectrometry and 1D, 2D NMR spectroscopy, and the new compound was identified as 3-O-{β-D-galactopyranosyl-（1→2）-[β-D-xylopyranosyl- （ 1→3 ）]-β-D-glucuronopyrannosyl } -28-O- { β-D-xylopyranosyl-（ 1 →3 ）-β-D-xylopyranosyl-（ 1 α4）-α-L-rhamnopyranosyl-（1→2）- [β-D-quinovopyranosyl-（1α4）]-β-D-fucopyranosyl} quillaic acid.
