Medicinal Flowers. Part 29. Acylated Oleanane‐Type Triterpene Bisdesmosides: Perennisaponins G, H, I, J, K, L, and M with Pancreatic Lipase Inhibitory Activity from the Flowers of Bellis perennis

The MeOH extract from the flowers of Bellis perennis was found to show pancreatic‐lipase inhibitory activity (IC50 455 μg/ml). From the extract, seven new triterpene saponins named perennisaponins G (1; IC50 163 μM), H (2; 137 μM), I (3; 147 μM), J (4; 148 μM), K (5; 223 μM), L (6; 81.4 μM), and M (7; 195 μM) were isolated as pancreatic lipase inhibitors. The stereostructures of 1–7 were elucidated on the basis of chemical and spectroscopic evidence.
