Title: Medicinal Flowers. XXXII. Structures of oleanane-type triterpene saponins, perennisosides VIII, IX, X, XI, and XII, from the flowers of Bellis perennis. Author: Morikawa T, Li X, Nishida E, Nakamura S, Ninomiya K, Matsuda H, Hamao M, Muraoka O, Hayakawa T, Yoshikawa M. Journal: Chem Pharm Bull (Tokyo); 2011; 59(7):889-95. PubMed ID: 21720043. Abstract: Five new triterpene saponins perennisosides VIII (1), IX (2), X (3), XI (4), and XII (5) were isolated from the MeOH-eluated fraction of the methanolic extract from the flowers of Bellis perennis. The MeOH-eluted fraction of the methanolic extract from the flowers of B. perennis was found to inhibit gastric emptying in olive oil-loaded mice at a dose of 200 mg/kg, per os (p.o.). The stereostructures of 1-5 were elucidated on the basis of chemical and spectroscopic evidence.[Abstract] [Full Text] [Related] [New Search]
