Abstract
Abstract
A bulk purification procedure is described for moniliformin, a mycotoxin produced by Fusarium moniliforme. The method involves methanol extraction of suitably molded maize, aqueous extraction of the methanol-f ree residue, ion exchange chromatography with a NaCl concentration gradient, desalination, and crystallization. A pKa value of 1.70 as well as molar absorptivities of 19100 (λ(H2O)max 229 nm), 5600 (λ(H2O)max 260 nm), and 4700 (λ(MeOH)max 260 nm) L/mole/cm are reported for moniliformin.
