Twenty‐nine strains from Fusarium section Liseola were screened for a zearalenone‐like compound using analytical thin‐layer chromatography (TLC). One metabolite had the same retention time on TLC and a similar multi‐peak ultraviolet (UV) spectrum to zearalenone. Mass spectral and nuclear magnetic resonance (1H, 13C, 1H‐13C heteronuclear multiple‐quantum coherence) analysis gave information that helped identify the compound as the Fusarium pigment 8‐O methyl bostrycoidin. The pigment was readily resolved from zearalenone with reversed‐phase high‐performance liquid chromatography analysis. Because this compound has a similar retention time, care should be exercised when using acid charring to visualize spots during zearalenone TLC analysis.
