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.
根据光谱证据和化学相关性,从 Bupleurum rotundifolium L.(伞形科)叶片中分离出两种新的三萜类化合物,即 rotundiogenin C (7)和 rotundiogenin F (14),分别鉴定为 oleana-11、13-(18)-diene-3β、16α、21α、28-tetraol 和 oleana-9、12-diene-3β、16α、21α、28-tetraol。
