The title compound, C27H37NO7, is a Daphniphyllum alkaloid isolated from a branch of Daphniphyllum macropodum Miq. All of the five-membered rings adopt envelope conformations while the six- and seven-membered ring adopt chair conformations. Classical intermolecular O-HO and weak C-HN hydrogen bonds are present in the crystal structure.
