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).

Keywords: 9,19-Cycloartane triterpenoids; Cimicifuga foetida; Cycloartane-type.
