One of the chromatographic fractions of an extract from Bellis Perennis has been analyzed using NMR. The major component of the fraction has been identified to be a novel triterpenoid saponin: 3-O-α-rhamnopyranosyl polygalacic acid 28-O-{α-rhamnopyranosyl (1→3)-β-xylopyranosyl(1→4)α-rhamnopyranosyl( 1→2)-[α-arabinofuranosyl(1→3)-4-O-acetyl-β-fucopyranoside]}.
