(-)-Tetrahydropalmatine monohydrate

The title compound, C21H25NO4.H2O, was isolated from the rhizome of Stefania rotunda L. of Vietnam and its structure elucidated. An S configuration was found at the asymmetric C13 atom of the (-)-enantiomer. The water molecule generates infinite helically arranged molecular columns around the screw axes in the z direction through intermolecular hydrogen bonds.
