Notes: In the title compound, 3β-(dimethylamino)-16α-hydroxy-14-methyl-4-methylene-9,19-cyclo-5α-pregnan-20-one monohydrate, C25H39NO2·H2O, the pentacyclo steroidal alkaloid is composed of three six-membered, one five-membered and one three-membered ring. The molecular dimensions are as expected. The structure is stabilized by hydrogen bonds involving H and O atoms of water and the alkaloid molecules, with strong N...O [2.829 (7) Å] and O...O [2.790 (6) and 2.949 (7) Å] interactions.
