Abstract: In the title solvate, C30H39NO5·CH4O {systematic name: 21-acetoxy-18,21-dihydroxy-5,6,16,18-tetramethyl-10-phenyl-6,7-epoxy-[11]cytochalasa-13,19-dien-1-one methanol solvate}, the organic molecule exhibits the tetracyclic terpenoid skeleton of cytochalasin, consisting of fused five-, six-, three- and 11-membered rings. The five-membered ring adopts an envelope conformation, while the six-membered ring is in a boat conformation. The epoxy O atom on the six-membered ring is pointing away from the five-membered ring. An interstitial methanol solvent molecule is hydrogen bonded to the cytochalasin molecules and intermolecular O-H
O and N-HO hydrogen bonds connect the molecules into infinite chains along the (
10) direction.
