(3S,7R)-7,14,16-Trihydroxy-3-methyl-3,4,5,6,7,8,9,10,11,12-decahydro-1H-2-benzoxacyclotetradecin-1-one.

The asymmetric unit of the title compound, C18H26O5, which is known as [alpha]-zearalanol, contains two molecules having the same conformation, with a r.m.s. deviation of less than 0.03 Å for all non-H atoms. In each independent molecule, an intramolecular O-H...O hydrogen bond stabilizes the molecular conformation. In the crystal, O-H...O hydrogen bonds link the molecules, forming infinite chains along [110] and [1-10].
