Lepidamine, the first aristolane-type sesquiterpene alkaloid from the Basidiomycete Russula lepida

A novel N-containing aristolane sesquiterpenoid compound, lepidamine (1), was isolated from the fruiting bodies of Basidiomycete Russula lepida. Its structure was established by spectroscopic means. It is the first aristolane-type sesquiterpene alkaloid isolated from nature.
