A new series of fumonisins, designated FP1-3, were isolated from a culture of Fusarium moniliforme (M-2285) grown on solid corn. The new compounds contain a 3-hydroxypyridinium moiety at the C-2 position of the eicosane backbone instead of the amine found in the B series of fumonisins. The new fumonisins were characterized by UV, LC-MS-MS, 1H NMR, and 13C NMR. LC-MS analysis of culture extracts indicates that the new fumonisins can occur at levels up to approximately one-third the amount of their amine-containing analogues (FB1, FB2, and FB3).
