(3<i>R</i>,6<i>R</i>,12<i>R</i>,20<i>S</i>,24<i>S</i>)-20,24-Epoxydammarane-3,6,12,25-tetraol dihydrate
TL;DRAbstract
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 tetra-hydro-furan ring has a conformation inter-mediate between half-chair and envelope. In the crystal, inter-molecular O-H⋯O hydrogen bonds link mol-ecules into a three-dimensional network. Intra-molecular O-H⋯O hydrogen bonds also occur.
