A comparative metabolite profiling approach based on gas chromatography � mass spectrometry was applied to investigate the impact of genetic background, environment and farming practice on the chemical composition of maize (Zea mays) grain. The metabolite profiling protocol involved sub-fractionation of the metabolites and allowed the assessment of about 300 distinct analytes from different chemical classes (polar to lipophilic). The evaluation of the results by sound statistics allowed to demonstrate the potential of metabolite profiling to evaluate variations in maize grain metabolite pools resulting from the interplay of environment, season and genotype and to put the results into the context of natural variability.
