In some European community countries up to 8% of the agricultural area is managed organically.The aim was to obtain a metabolite profile for wheat (Triticum aestivum L.) grains grown undercomparable organic and conventional conditions. These conditions cannot be found in plant materialoriginating from different farms or from products purchased in supermarkets. Wheat grains from along-term biodynamic, bioorganic, and conventional farming system from the harvest 2003 fromSwitzerland were analyzed. The presented data show that using a high throughput GC-MS technique,it was possible to determine relative levels of a set of 52 different metabolites including amino acids,organic acids, sugars, sugar alcohols, sugar phosphates, and nucleotides from wheat grains. Withinthe metabolites from all field trials, there was at the most a 50% reduction comparing highest andlowest mean values. The statistical analysis of the data shows that the metabolite status of the wheatgrain from organic and mineralic farming did not differ in concentrations of 44 metabolites. This resultindicates no impact or a small impact of the different farming systems. In consequence, we did notdetect extreme differences in metabolite composition and quality of wheat grains.
