Phenolic acid content and composition have been determined in 26 wheat genotypes grown in Hungary over three consecutive years and at three additional locations (France, United Kingdom, and Poland) during the third year. Fractions comprising free, soluble conjugated, and bound phenolic acids were analyzed using HPLC with measurements being made for individual phenolic acids in each fraction. Statistically significant differences in phenolic acid content occurred across the different growing locations with the average total phenolic acid content being highest in the genotypes grown in Hungary. The growth year in Hungary also had a large impact, especially on the free and conjugated phenolic acid contents. Certain genotypes were more resistant to environmental impacts than others. Of the genotypes with high levels of total phenolic acids, Lynx, Riband, Tommi, and Cadenza were most stable with respect to their total contents, whereas Valoris, Herzog, and Malacca, also high in phenolic acid content, were least stable. Of the three fractions analyzed, the free and conjugated phenolic acids were most variable and were also susceptible to the effect of environment, whereas bound phenolic acids, which comprised the greatest proportion of the total phenolic acids, were the most stable.
在三年的时间里，对 26 种在匈牙利种植的小麦品种进行了连续三年的研究，并在第三年在另外三个地点（法国、英国和波兰）进行了研究。采用 HPLC 分析了包含游离、可溶结合和结合酚酸的分数，并对每个分数中的单个酚酸进行了测量。酚酸含量在不同的生长地点存在显著差异，匈牙利种植的基因型的总酚酸含量最高。匈牙利的生长年份也有很大的影响，尤其是对游离和结合酚酸的含量。与其他品种相比，某些品种对环境影响的抵抗力更强。在总酚酸含量较高的基因型中，Lynx、Riband、Tommi 和 Cadenza 就总含量而言最稳定，而 Valoris、Herzog 和 Malacca 酚酸含量也较高，最不稳定。在分析的三个分数中，游离和结合酚酸的变化最大，而且容易受到环境的影响，而占总酚酸比例最大的结合酚酸则最稳定。
