Solvolysis procedures for the determination of bound residues of the mycotoxin deoxynivalenol in fusarium species infected grain of two winter wheat cultivars preinfected with barley yellow dwarf virus.


A trichloroacetic acid treatment at 140 degrees C for 40 min was successfully established as a suitable solvolysis procedure for the recovery of bound deoxynivalenol or its derivatives in Fusarium-infected plants. Deoxynivalenol itself was not decomposed in the procedure. The derivative 15-acetyl-deoxynivalenol was chosen as a model compound for setting… (More)
