Comprehensive and Comparative Metabolomic Profiling of Wheat, Barley, Oat and Rye Using Gas Chromatography-Mass Spectrometry and Advanced Chemometrics

Abstract: Beyond the main bulk components of cereals such as the polysaccharides and proteins, lower concentration secondary metabolites largely contribute to the nutritional value. This paper outlines a comprehensive protocol for GC-MS metabolomic profiling of phenolics and organic acids in grains, the performance of which is demonstrated through a comparison of the metabolite profiles of the main northern European cereal crops: wheat, barley, oat and rye. Phenolics and organic acids were extracted using acidic hydroly… Show more

“…Metabolic composition is highly variable in a wide variety of plants including major crops like wheat [16], rice [17], maize [15], and cassava [14]. These metabolic changes in plants have also occurred due to progressive water deficit conditions accompanied by lower leaf water potentials [18].…”

“…For understanding of sorghum chemical profile, many techniques have been used, including gas chromatography attached to mass spectrometry (CG-MS), 6 electrophoresis in polyacrylamide gel (SDS-PAGE) 7 and high-performance liquid chromatography with evaporative light scattering detector (ELSD) detector. 8 All of those techniques, however, require extensive laboratory preparation, lengthy analysis and high operational costs, making it difficult to perform them.…”
