Sumario:The title compound, C(30)H(52)O(5)·2H(2)O, 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.
