ABSTRACT

Egypt is considered one of the main producers of date fruits in the world. Tamr dry date is widely cultivated in Upper Egypt, however, investigating the chemical components and biological activities of such common variety has not been performed yet. In this study, the chemical components of the Tamr variety and its biological activities were investigated. Results showed that the percentages of sugar, dietary fibers, metal, protein were 61.0%, 13.7%, 2.1, and 2.6%, respectively. Total phenolic and flavonoids were 17.6 and 2.3 mg/100 g, respectively. 17 amino acids, 8 metals, 15 fatty acids, 30 terpenes, vitamins (A, B1, B2, B3), and 5 flavonoids were identified. The presence of phenolics and flavonoids in ethyl acetate extract resulted in high biological activity than chloroform and methanolic extracts. The biological activity of chloroform extract could be ascribed to the presence of polyunsaturated fatty acids and terpenes. These results are in good agreement with the chemical-biological relationships.

摘要

埃及被认为是世界上枣果的主要生产国之一。Tamr 干枣在上埃及广泛种植，但尚未对这种常见品种的化学成分和生物活性进行调查。在这项研究中，研究了 Tamr 品种的化学成分及其生物活性。结果表明，糖、膳食纤维、金属、蛋白质的百分比分别为61.0%、13.7%、2.1和2.6%。总酚类和类黄酮分别为 17.6 和 2.3 毫克/100 克。鉴定出 17 种氨基酸、8 种金属、15 种脂肪酸、30 种萜烯、维生素（A、B1、B2、B3）和 5 种黄酮类化合物。乙酸乙酯提取物中酚类和黄酮类化合物的存在导致比氯仿和甲醇提取物更高的生物活性。氯仿提取物的​​生物活性可归因于多不饱和脂肪酸和萜烯的存在。这些结果与化学-生物学关系非常吻合。
