L-Tryptophan (tryptophan) is an essential amino acid in humans. It has important roles as a precursor of different bioactive compounds. Based on previous studies in which tryptophan has been shown to be present in fresh cherries, the aim of the present work was to analyze the tryptophan content of a Jerte Valley cherry-based product. A previously optimized method of analysis of tryptophan was used, ie, high-performance liquid chromatography with fluorescence detection (HPLC/FL). As expected, HPLC/FL technique permitted to detect and quantify the tryptophan content in a different matrix rather than fresh cherries. In fact, the Jerte Valley cherry-based product contained 69.54 ± 10.64 ppm of tryptophan, thereby showing that this product is a good source of tryptophan. In summary, it has been proven that the Jerte Valley cherry-based product is rich in tryptophan and may be indicated as a supply of this essential amino acid as well as having potential health benefits for conditions where tryptophan is necessary.
L-色氨酸是人体必需的氨基酸。它作为不同生物活性化合物的前体发挥着重要作用。基于此前已证实色氨酸存在于新鲜樱桃中的研究，本研究的目的是分析一种基于赫尔特谷樱桃的产品中的色氨酸含量。采用了一种先前优化的色氨酸分析方法，即高效液相色谱-荧光检测法（HPLC/FL）。不出所料，HPLC/FL技术能够检测并定量不同基质（而非新鲜樱桃）中的色氨酸含量。事实上，基于赫尔特谷樱桃的产品中色氨酸含量为69.54±10.64 ppm，这表明该产品是色氨酸的良好来源。总之，已证实基于赫尔特谷樱桃的产品富含色氨酸，可作为这种必需氨基酸的供应源，并且对于需要色氨酸的病症可能具有潜在的健康益处。
