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→4)-α-L-rhamnopyranosyl-(l→2)-[β-D-quinovopyranosyl-(1→4)]-β-D-fucopyranosyl} quillaic acid.

Key words: Silene rubicunda, Triterpenoid saponin, Saponin
