Four new 9,19‐cyclolanostane‐type triterpenes ( 1 – 4 ), were isolated from the rhizomes of Cimicifuga foetida . On the basis of spectroscopic analysis, their chemical structures were elucidated as 1,7‐dien‐cimigenol‐3,12‐dione ( 1 ), 1‐en‐cimigenol‐3,11‐dione ( 2 ), 11 ( ‐hydroxy‐7‐en‐cimigenol‐3‐one ( 3 ), and (20 R ,24 R )‐24,25‐epoxy‐11 ( ‐hydroxy‐7‐en‐9,19‐cyclolanost‐3,16,23‐trione ( 4 ).
