title: [A new saponin from Koelreuteria paniculata].
abstract: To investigate the chemical constituents of seeds of Koelreuteria paniculata Laxm. , components were separated by means of solvent extraction and chromatography on C18, the structure of compound was determined by spectral analysis and chemical evidences. One saponin was obtained and identified as 28-O-isopentyryl-3beta, 16alpha, 22beta, 28-tetrahydroxyl-oleanane-3-O-[ alpha-L-rhamnopyranosyl- ( 1-->3) -betaD-galactopyranosyl-( 1--->4' )]-3betaD-galacturonopyranoside, named paniculata saponin C. This saponin is a new compound.
