Prevention strategies for trichothecenes
Toxicology Letters, 2004Contamination of cereal commodities with mycotoxins represents a significant hazard to consumer health and has thus received increasing attention from food safety authorities and legislators. For trichothecenes, and deoxynivalenol (DON) in particular, the imminent implementation of legislative limits has focused attention on ways to prevent entry of ...

Determination of trichothecenes in cereals
Journal of Chromatography A, 1999An effective method for the determination of seven trichothecenes-deoxynivalenol (DON), nivalenol (NIV), T-2 tetraol (T-24), fusarenon-X (FUS-X), diacetoxyscirpenol (DAS), T-2 toxin (T-2), HT-2 toxin (HT-2) in cereals is presented. Gel permeation chromatography on Bio-Beads S-X3 was used for clean-up of acetonitrile-methanol extract.

Chemical Synthesis of the Trichothecenes
1985That research in the trichothecene field is an area of intense interest cannot be disputed. In the years 1982 and 1983, there were more than 500 publications dealing with this subject, including more than 30 reviews. In addition, a comprehensive monograph has recently appeared (151).

A yeast bioassay for trichothecenes
Natural Toxins, 1999Like all eucaryotic cells, yeasts are sensitive to trichothecenes, especially T-2 toxin and verrucarin A. Based on this sensitivity, a yeast bioassay was developed to evaluate the toxicity of corn samples. The bioassay was optimized using spiked maize extracts. The toxicity of samples was defined as toxicity equivalent to a certain concentration of T-2

Targeting Trichothecene Biosynthetic Genes
2016Biosynthesis of trichothecenes requires the involvement of at least 15 genes, most of which have been targeted for PCR. Qualitative PCRs are used to assign chemotypes to individual isolates, e.g., the capacity to produce type A and/or type B trichothecenes. Many regions in the core cluster (consisting of 12 genes) including intergenic regions have been

Trichothecenes and their analysis
Journal of the American Oil Chemists' Society, 1979AbstractThe analysis of foods and feeds for the naturally occurringFusarium produced trichothecenes is reviewed. Each major step (extraction, purification and detection‐quantitation) is discussed. Although none of the extraction solvents has been thoroughly evaluated, aqueous metanol is the preferred system in most of the published procedures.

HPLC-MS-Method for A-Trichothecenes
Mycotoxin Research, 2001Gaschromatography with electron capture detection belongs to the most important methods for analysing the A-trichothecenes T-2 toxin, HT-2 toxin and diacetoxyscirpenol. The need of a derivatisation for these mycotoxins prior detection is the main disadvantage of this method.

Influence of processing on trichothecene levels
Toxicology Letters, 2004Trichothecene mycotoxins frequently occur in cereal grains that are intended for food production. The process of converting grains into food and drinks for consumers has significant effects on the levels of toxins in the final food. Surveillance of retail food and drinks of cereal origin demonstrates that trichothecenes do survive the production ...

State of the art of trichothecenes analysis
Toxicology Letters, 2004Methods to analyze trichothecenes should be fast, reliable and economical. The known methods can be divided into two categories: the 'instrumental methods' as gas chromatography (GC) and high performance liquid chromatography (HPLC) and the so called 'fast methods' like thin layer chromatography (TLC), enzyme-linked immunosorbant analyses (ELISA) and ...
