Four new fumonisins, an isomer of fumonisin C1 (iso-FC1) (1) and three N-acetyl derivatives of hydroxylated fumonisin C1 (OH-FC1) (2), fumonisin C1 (FC1) (3), and iso-FC1 (4) were isolated from wheat cultures of Fusarium oxysporum. One of the hydroxy groups of compound 1 is at C-3 instead of C-4 for FC1. Compounds 2-4 are similar in structure to OH-FC1, FC1, and iso-FC1, respectively, except for the presence of an acetyl group at the amine of C-1.
从尖孢镰刀菌的小麦培养物中分离出4种新的伏马菌素，即伏马菌素C1的异构体（异-FC1）（1）以及羟基化伏马菌素C1（OH-FC1）的3种N-乙酰基衍生物（2）、伏马菌素C1（FC1）（3）和异-FC1（4）。化合物1的一个羟基位于C-3位，而非FC1中的C-4位。化合物2-4的结构分别与OH-FC1、FC1和异-FC1相似，只是在C-1的胺基处存在一个乙酰基。
