Abstract

The title compound, a novel triterpenoid, C30H48O4·CH4O, was isolated from the rhizome of Astilbe chinensis (Maxim.) Franch. et Sav. It contains five fused six‐membered rings, which adopt half‐chair conformations. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecules, forming an extensive network, which may be effective in the stabilization of the structure.
