Phytochemical analysis of the rhizomes of Cimicifuga racemosa (Ranunculaceae) resulted in the isolation of twelve cycloartane glycosides (1--12), including four new ones (4--6, 12). The structures of the new compounds were determined by spectroscopic analysis, including two-dimensional (2D) NMR data, and chemical methods. The isolated compounds were evaluated for their cytotoxic activities against
