A single crystal of iridoid related compound isoeucommiol was obtained through NaBH4 reduction of aucubigenin which was formed by enzymatic hydrolysis of aucubin. Its structure and stereochemistry were determined by X-ray diffraction. The crystal adopts an envelope conformation, presenting a triclinic system, space group P1 with Z = 1, unit cell dimensions a = 5.4158(13) Å, b = 6.5251(15) Å, and c = 7.1555(17) Å. Moreover, extensive network of intermolecular O–H···O hydrogen bonds in crystal lattices can be observed.
