标题化合物C30H52O5·2H2O是从西洋参皂苷中提取分离的假人参皂苷F11降解得到的。三个六元环呈椅形。五元环处于包络构象，四氢呋喃环具有介于半椅式和包络构象之间的中间构象。在晶体中，分子间的O—H⋯O氢键将分子连接成三维网络。分子内也会出现O—H⋯O氢键。
The title compound, C30H52O5·2H2O, was degraded from pseudoginsenoside F11 which was extracted and seperated from Panax quinquefolium saponin. The three six-membered rings are in chair conformations. The five-membered ring is in an envelope conformation and the tetrahydrofuran ring has a conformation intermediate between half-chair and envelope. In the crystal, intermolecular O—H⋯O hydrogen bonds link molecules into a three-dimensional network. Intramolecular O—H⋯O hydrogen bonds also occur.
