Abstract:: The aim of this study was to assess the production of secondary metabolites of Alternaria species isolated from grape berries and determined the occurrence of Alternaria mycotoxins in vitro and in dried berries. Direct morphological examination on different media was used for identification and HPLC/MS method for quantification of Alternaria mycotoxins. We isolated A. alternata and A. tenuissima and randomly selected strains in vitro and in dried berries. In vitro we identified the production of Alternaria metabolites, included mycotoxins: alternariol, alternariol methylether, tenuazonic acid. Beside that one in dry berries were in measurable concentrations: macrosporin A, tentoxin and altenuete (I, II).
