title: Six New 9,19-Cycloartane Triterpenoids from Cimicifuga foetida L.
abstract: Six new 9,19-cycloartane triterpene derivatives, as well as 3 known analogues (7-9), were isolated from the roots of Cimicifuga foetida L. Their structures were established on the basis of extensive spectroscopic analyses (IR, UV, ORD, HRESIMS, 1D and 2D NMR).
