A total of 22 triterpene glycosides, including 10 new compounds (1−10), were isolated from the underground parts of Caulophyllumthalictroides. The structures of the new glycosides were determined on the basis of extensive spectroscopic analyses, including two-dimensional (2D) NMR data, and of hydrolytic cleavage followed by chromatographic or spectroscopic analyses. All 22 compounds were evaluated
