Stability of fumonisins (FB(1) and FB(2)) in solution
The stability of fumonisins FB(1) and FB(2) during six week storage was studied in acetonitrite:water (1:1) and methanol at four storage temperatures (-18, 4, 25 and 40 C). Samples were analysed by HPLC with fluorescence detection. Decomposition of fumonisins was evident in a methanol solution at 4, 25 and 40 C, whereas no losses were observed in samples stored at -18 C. Both fumonisins were stable in acetonitrite:water solution at any of the four storage temperatures. This investigation concluded that acetonitrite:water (1:1), unlike methanol, is a suitable solvent for fumonisin reference solutions.
