A Greener, Quick and Comprehensive Extraction Approach for LC-MS of Multiple Mycotoxins

Published: August 24, 2017
Summary
1. Introduction Mycotoxins are toxic secondary metabolites of certain moulds whose occurrence in food and feed is difficult to avoid. They present a potential risk to the health of consumers. Therefore, many countries have regulated the occurrence of mycotoxins [1,2]. A wealth of methods of analysis exists to enforce these regulations. Many of these methods rely on mixtures of acetonitrile (AC...

Good day, Please can I also extract and analyse masked fusarium mycotoxins in maize using this approach? Theodora

Since the masked mycotoxins are host plant metabolites to make mycotoxins more water soluble it is unlikely that they will extract well into EtOAc. I never tested it, though.

Please which internal standards did you use. Is C isotope-labeled mycotoxin standards ok? Also after extraction, is it possible to store the supernatant and under which conditions, before sending them to Research Institute for LC/MS analyses.

All the information you are looking for is described in the Materials&Methods section of the paper. The ISTD compounds are 13C-labelled isotopologues of the mycotoxins you are testing for.
