Inoculated or non-inoculated naked barley and emmer cultivars were investigated with regard to their influence on phenolic acid profiles and their arabinoxylan content. Two groups of phenolic compounds were differentiated-methanol-soluble and hydrolyzable covalent-bound phenolic compounds. Chromatographic methods were applied for their analysis. The results showed ferulic acid as the predominant phenol in both total and covalent-bound fractions. The inoculation significantly reduced the ferulic acid content within a range of 5.6-6.6% in the two cereals and all their cultivars. Naked barley cultivars additionally contained the flavonoid catechin in the soluble fraction. The innoculation led here to a significant increase in the catechin content of about 4.5%. These results document an induction of the synthesis of catechin in naked barley after artificial Fusarium infection, whereas the ferulic acid content declined.
研究了接种和未接种的裸大麦和粗麦品种，以探讨它们对酚酸谱和阿拉伯木聚糖含量的影响。将两组酚类化合物区分开来——甲醇可溶和可水解共价结合的酚类化合物。应用色谱方法对其进行分析。结果表明，两种谷物及其所有品种的总酚和共价结合酚类化合物中，阿魏酸均为主要酚类化合物。接种在两种谷物的范围内使阿魏酸含量降低了 5.6-6.6%。裸大麦品种在可溶部分还含有类黄酮儿茶素。接种后，儿茶素的含量显著增加了约 4.5%。这些结果证明，在人工镰刀菌感染后，裸大麦中儿茶素的合成被诱导，而阿魏酸含量下降。
