Abstract
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.
