. The occurrence of culmorin and hydroxy-culmorins in cereals.

Forty-five  samples  of naturally  contaminated  grain,  barley,  wheat  and oats,  three  samples  of mixed  feed, and 16  samples of grain  artificially  inoculated  with  Fusarium  culmorum  during  the flowering  stage  were  analysed for DON,  3-acetylDON,  culmorin  and hydroxy-culmorins.  Theamount  of each of culmorin,  5-, 12-,  14- and  15-hydroxy-culmorin  and  one  unknown  hydroxy-culmorin  were  determined  relative  to  the  amount  of  DON  plus  3- acetyIDON  for  each  sample.  There  was  a stron  correlation  beween t he amount  of DON  present in  the gran  and  the  amount  fof  culmorin  and  hdroxy-culmorins  present.  The  ratio  of each  of the culmorin  compounds  relative  to the  amount  of DON  compounds  were  in the  same  range  in the grain artificially  inoculated  by  F.  culmorum  as  found  in  an  earlier  study  for F. culmorum  strains  cultivated  on rice,  while  the hydroxy –culmorin  profile  in the  naturally  contaminated  grain  was  more  similar  to that  found  for the F.  graminearum  cultures in the same  study.
