Date palm fruits and by-products such as seeds are a source of various elements with significant nutritional values like fibres, minerals, essential fatty acids, amino acids and phenolic compounds. The experimental part was carried out on date palm seeds from Bent Kbala cultivar, the chemical composition of the organic fraction was determined using the method of UV-visible spectrophotometer, thin layer chromatography (TLC) and high-performance liquid chromatography-diode array detection (HPLC-DAD). The results revealed the presence of catechic tannins and approximately 17 phenolic compounds, including two compounds, which were identified for the first time in the date palm sub-product, especially in seeds such as naringenin and rutine. The assessment of the antioxidant potential shows that date palm seeds have a significant potential compared to standard antioxidants commonly used in cosmetics and neutraceutics industries.
椰枣果实及其种子等副产品是多种具有重要营养价值的元素的来源，如纤维、矿物质、必需脂肪酸、氨基酸和酚类化合物。实验部分使用的是来自本特·克巴拉品种的椰枣种子，采用紫外可见分光光度计法、薄层色谱法（TLC）和高效液相色谱-二极管阵列检测法（HPLC-DAD）测定有机部分的化学成分。结果显示存在儿茶素单宁和大约17种酚类化合物，其中包括两种首次在椰枣副产品中鉴定出的化合物，特别是在种子中，如柚皮素和芦丁。抗氧化潜力评估表明，与化妆品和营养保健品行业常用的标准抗氧化剂相比，椰枣种子具有显著的潜力。
