A new toxic sesterterpene, named fusaproliferin, was purified from corn kernel cultures (120 ms/kg dry culture) of a strain of Fusarium proliferatum isolated from com ear rot in northern Italy. The strain, designated ITEM‐1494, also produced fumonisin B., (1.500 mg/kg dry culture) and beauvericin (90 mg/kg dry culture), but not moniliformin. To monitor toxicity, the brine shrimp assay was used throughout the isolation procedure. Fusaproliferin had a molecular formula of C27H40O5, and it is the first sesterterpene isolated from a Fusarium species. © 1995 Wiley‐Liss, Inc.
