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).
从在固体玉米上生长的串珠镰刀菌（M-2285）培养物中分离出了一系列新的伏马毒素，命名为FP1 - 3。这些新化合物在二十烷主链的C-2位置含有一个3-羟基吡啶鎓部分，而不是伏马毒素B系列中发现的胺基。通过紫外光谱（UV）、液相色谱 - 串联质谱（LC-MS-MS）、氢核磁共振（1H NMR）和碳核磁共振（13C NMR）对新的伏马毒素进行了表征。对培养物提取物的液相色谱 - 质谱分析表明，新伏马毒素的含量可能高达其含胺类似物（FB1、FB2和FB3）含量的约三分之一。
