Determination of the profiles of secondary metabolites characteristic of Alternaria strains isolated from tomato
Background: Many Alternaria species have been studied for their ability to produce bioactive secondary metabolites, such as tentoxin (TEN), some of which have toxic properties. The main food contaminant toxins are tenuazonic acid, alternariol (AOH), alternariol monomethyl ether (AME), altenuene, and...

Aims: To determine the profiles of secondary metabolites characteristic of Alternaria strains isolated from tomato for their chemotaxonomic classification. Methods: The profiles of secondary metabolites were determined by HPLC MS. Results: The Alternaria isolates obtained from spoiled tomatoes belong, according to their morphological characteristics, to the species groups Alternaria alternata, Alternaria tenuissima and Alternaria arborescens, with A. tenuissima being the most frequent. The most frequent profiles of secondary metabolites belonging to the species groups A. alternata (AOH, AME, TEN), A. tenuissima (AOH, AME, TEN, tenuazonic acid) and A. arborescens (AOH, AME, TEN, tenuazonic acid) were determined, with some isolates of the latter being able to synthesize AAL toxins. Conclusions: Secondary metabolite profiles are a useful tool for the differentiation of small spored Alternaria isolates not easily identifiable by their morphological characteristics. © 2013 Revista Iberoamericana de Micología. 2014 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_11301406_v31_n2_p119_BenavidezRozo http://hdl.handle.net/20.500.12110/paper_11301406_v31_n2_p119_BenavidezRozo |
