Punctatin A (antibiotic M95464): X-ray crystal structure of a sesquiterpene alcohol with a new carbon skeleton from the fungus, Paronia punctata

Physical methods and X-ray diffraction analysis have been used to establish the structure of a novel trihydroxysesquiterpene, punctatin A, produced, with a series of related compounds, by the dung fungus Poronia punctata(Linnaeus ex Fries).
