| Abstract: | 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. |
