Abstract

Two new 9,19-cycloartane triterpene glycosides 1-2, together with four known compounds—26-deoxyactein (3), actein (4), 7,8-didehydro-26-deoxyactein (5) and cimiaceroside B (6)—were isolated from the rhizome of Cimicifuga foetida. The new triterpene glycosides were identified as 23-O-methyl-24-deoxy-2'-O-(3''-methylmalonyl)-cimiaceroside B (1) and 2'-O-(3''-methylmalonyl)actein (2) based on analysis of their spectral data and chemical reactions.
