title: Triterpene glycosides from the underground parts of Caulophyllum thalictroides.
abstract: A total of 22 triterpene glycosides, including 10 new compounds (1-10), were isolated from the underground parts of Caulophyllum thalictroides. 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 for cytotoxicity against HL-60 human leukemia cells. The triterpene monodesmosides based on oleanolic acid (1 and 11-16) showed cytotoxic activity against HL-60 cells with IC(50) values that ranged from 3.4 to 15.9 microg/mL.
