Modified QuEChERS Based on Mixed Adsorbent Cleanup of Mycotoxins in Corn [PDF]

Journal of Chemistry, 2020
In order to analyze the mycotoxins in corn, the modified QuEChERS high-performance liquid chromatography was applied to extract, clean up, and detect mycotoxins in a nonpolar system. The impurities such as fat and protein were removed from the corn sample, and the impurities in the sample solution have almost no effect on extraction efficiency.

Development of an Analytical Method for Simultaneous Determination of the Modified Forms of 4,15-Diacetoxyscirpenol and their Occurrence in Japanese Retail Food

Toxins, 2018
4,15-Diacetoxyscirpenol (4,15-DAS) is a type A trichothecene mycotoxin produced by Fusarium species. Four modified forms of 4,15-DAS including 7-hydroxydiacetoxyscirpenol, 7,8-dihydroxydiacetoxyscirpenol, 4β,8α,15-triacetoxy-3α,7&alpha ...

Chemical Synthesis of Deoxynivalenol-3-β-d-[13C6]-glucoside and Application in Stable Isotope Dilution Assays

Molecules, 2016
Modified mycotoxins have been gaining importance in recent years and present a certain challenge in LC-MS/MS analysis. Due to the previous lack of a labeled isotopologue of the modified mycotoxin deoxynivalenol-3-glucoside, in our study we synthesized ...

Further insight into the potential toxicity of zearalenone-14-glucoside based on toxicokinetics, tissue distribution, transformation, and excretion in rats

Ecotoxicology and Environmental Safety, 2022
Bioaccumulation and biotransformation are critical factors that affect the release of easily metabolizable chemicals to cause human toxicity. The glucoside-type modified mycotoxin Zearalenone-14-Glucoside (Z14G) has attracted global attention for its ...

Detoxification of Deoxynivalenol via Glycosylation Represents Novel Insights on Antagonistic Activities of Trichoderma when Confronted with Fusarium graminearum

Toxins, 2016
Deoxynivalenol (DON) is a mycotoxin mainly produced by the Fusarium graminearum complex, which are important phytopathogens that can infect crops and lead to a serious disease called Fusarium head blight (FHB).

Mycotoxin Occurrence in Maize Silage—A Neglected Risk for Bovine Gut Health?

Toxins, 2019
Forages are important components of dairy cattle rations but might harbor a plethora of mycotoxins. Ruminants are considered to be less susceptible to the adverse health effects of mycotoxins, mainly because the ruminal microflora degrades certain ...

Prevalent Human Gut Bacteria Hydrolyse and Metabolise Important Food-Derived Mycotoxins and Masked Mycotoxins

Toxins, 2020
Mycotoxins are important food contaminants that commonly co-occur with modified mycotoxins such as mycotoxin-glucosides in contaminated cereal grains. These masked mycotoxins are less toxic, but their breakdown and release of unconjugated mycotoxins has ...

Varietal differences in deoxynivalenol and its glucoside (modified mycotoxin) content in forage corn inoculated with Fusarium graminearum

JSM Mycotoxins, 2019
To identify varietal differences in deoxynivalenol (DON) and deoxynivalenol-3-glucoside (D3G) content in forage corn in Japan, field experiments involving fungal inoculations were conducted.
