Abstract: The title compound [systematic name: (20R,24R)-11,24,25-trihydroxy-9,19-cyclolanost-7-ene-3,16,23-trione], C₃₀H₄₄O₆, is a cycloartenol triterpenoid which was isolated from the rhizomes of Cimicifuga racemosa. The molecule contains three six-membered rings adopting chair and distorted boat conformations, a five-membered ring exhibiting an envelope conformation and a three-membered ring. The molecules are linked by three hydrogen bonds, forming a two-dimensional structure parallel to the (001) plane.
