Threenew 15-hydroxy-trinor type (1-3), a new tetranor type (4), and two new 3,15,23,24-tetrahydroxy-16-oxo type cycloartaneglycosides (5, 6) were isolated from the rhizome of Cimicifuga heracleifolia KOMAROV. Their structures were determined by the use of the 2D-NMR techniques and chemical evidence.
