From the culture filtrate of a strain of A. fumigatus, known to produce fumigatin only, 5 other quinones were isolated by chromatography and structurally determined. One of these is the well-known fungal metabolite spinulosin, and the others were shown to be 3-hydroxy-2,5-toluquinone, 3,6-dihydroxy-2,5-toluquinone, 3,4-dihydroxy-2,5-toluquinoen, and 4-hydroxy-3-methoxy- 2,5-toluquinone.
