چکیده
In the title compound, C(30)H(52)O(5), the three six-membered rings are in chair conformations, the five-membered ring is in an envelope form and the tetra-hydro-furan ring has a conformation inter-mediate between half-chair and sofa. Intra-molecular O-H⋯O hydrogen bonds may influence the conformation of the mol-ecule. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds, forming a three-dimensional network.

متن کاملIdentification of 20(S)-protopanaxadiol metabolites in human liver microsomes and human hepatocytes.
20(S)-Protopanaxadiol (PPD, 1) is one of the aglycones of the ginsenosides and has a wide range of pharmacological activities. At present, PPD has progressed to early clinical trials as an antidepressant. In this study, its fate in mixed human liver microsomes (HLMs) and human hepatocytes was examined for the first time. By using liquid chromatography-electrospray ionization ion trap mass spect...
