Vanderbylia robiniophila (Huaier in Chinese) has been used as a traditional herbal medicine China for over 1600 years. However, the secondary metabolites of V. have not systematically examined. Corresponding chemical investigation this study led to discovery two new compounds, (22E, 24R)-6β, 7α-dimethoxyergosta-8(14), 22-diene-3β, 5α-diol (1) and vanderbyliolide A (8), along with eight known on...

The title ergosterol compound, C(28)H(44)O(4)·H(2)O, is composed of four fused rings (three six-membered and one five-membered) and a side chain. It is a derivative of ergosterol and was isolated from a marine-derived halotolerant fungus, Cladosporium cladosporioides PXP-49. In the crystal, mol-ecules are assembled by classical O-H⋯O hydrogen bonds, forming a two-dimensional network, with base ...

In the title mol-ecule, C(28)H(44)O, the two six-membered rings have a chair conformation and the two five-membered rings haveenvelope conformations. The crystal packing exhibits no short inter-molecular contacts. The absolute configuration was assigned to correspond with that of the known chiral centres in a precursor molecule, which remained unchanged during the synthesis of the title compound.
