Two new triterpenoids, rotundiogenin C (7), and rotundiogenin F (14), isolated from the leaves of Bupleurum rotundifolium L. (Umbelliferae), were identified as oleana-11, 13-(18)-diene-3β, 16α, 21α, 28-tetraol, and oleana-9, 12-diene-3β, 16α, 21α, 28-tetraol, respectively, on the basis of spectroscopic evidence and chemical correlations.
