Abstract: The title compound, C₃₀H₄₈O₃·CH₄O, is a cytotoxic and apoptosis-inducing triterpenoid which was isolated from the rhizome of Astilbe chinensis. The molecule is composed of five six-membered rings. The cyclohexene ring adopts a slightly distorted half-chair conformation and the cyclohexane rings adopt chair conformations. The hydroxy and carboxy groups both serve simultaneously as hydrogen-bond donors and acceptors, forming molecular chains.
