Abstract Four new 9, 19-cycloartane triterpenoids, cimilactone E(1), cimilactone F(2), 20-O-(E)-butenoyl-23-epi-26-deoxyactein(3), and 20, 12β-O-diacetylcimiracemonol-3-O-β-D-xylopyranoside(4), together with four known constituents(5-8) were isolated from the roots of Cimicifuga foetida. The new structures were elucidated by extensive spectroscopic analysis. In addition, compounds 7 and 8 showed significant Wnt signaling pathway inhibitory activity, with IC50 values of 3.33 and 13.34 μM, respectively, using the luciferase reporter gene assay.
