Bellissaponins BA1 and BA2, acylated saponins from Bellis perennis
Phytochemistry 30 (1991)
627-631
Two novel acylated triterpenoid saponins were isolated from Bellis perennis. The structures of these have been elucidated as 3-O-α-l-rhamnopyranosyl- and 3-O-β-d-glucopyranosyl-2β,3β,16α,23-tetrahydroxyolean-12-en-28-oic acid-28-O-α-l-rhamnopyranosyl(1→3)-β-d-xylopyranosyl(1→4)-α-l-rhamnopyranosyl(1→2)-[E-buta-2-enoic acid(1→4)]-β-d-fucopyranoside by means of high field 1D and 2D NMR spectroscopic methods without recourse to derivatization or comparison with previous data.
