The title compound (cimifugin), C(16)H(18)O(6)·0.5CH(3)OH, was isolated from the rhizome of Actaea asiatica Hara. The asymmetric unit contains two independent mol-ecules and a solvent methanol mol-ecule. The five-numbered ring adopts an envelope conformation in each molecule. Intra- and inter-molecular O-H⋯O hydrogen bonds stabilize the crystal structure.
标题化合物(升麻苷),C(16)H(18)O(6)·0.5CH(3)OH,从亚洲类叶升麻(Actaea asiatica Hara)的根茎中分离得到。不对称单元包含两个独立的分子和一个溶剂甲醇分子。每个分子中的五元环呈信封构象。分子内和分子间的O-H⋯O氢键稳定了晶体结构。
