在标题分子C30 H52 O 4中，三个六元环均为椅型构象，环戊烷环为信封型构象，四氢呋喃环为介于半椅型和沙发型之间的中间构象。在晶体中，分子通过分子间的O-H-O氢键连接成螺旋链沿着[100]。分子内还存在两个O-H-O氢键。四氢呋喃环的一个C原子和其连接的H原子在两组位点上同样无序。
In the title molecule, C30H52O4, the three six-membered rings are in chair conformations, the cyclopentane ring is in an envelope form and the tetrahydrofuran ring has a conformation intermediate between half-chair and sofa. In the crystal, molecules are linked by intermolecular O—H⋯O hydrogen bonds into helical chains along [100]. Two intramolecular O—H⋯O hydrogen bonds are also present. One C atom of the tetrahydrofuran ring and its attached H atoms are equally disordered over two sets of sites.
