The present study describes the chemical composition and antioxidant components of date fruits, date seeds and palm shell. Tocopherol, phenolic compounds, benzoic acid, cinnamic acid, quercetin and kaempferol of date fruits, date seeds and palm shell were determined by HPLC. Date fruits contained high amounts of total phenols 2515.6 mg/ 100 g and tocopherol 22.722 μg/ 100 g, while palm shell contained high amounts of total tannins 1728.03 mg/ 100 g. Date seeds contained high amounts of kaempferol 14.878 mg/ 100 g and protocattechuic acid 6.672 mg/ 100 g. The antioxidant activity of date fruits, date seeds and palm shell were evaluated and exhibited 91.87, 81.85 and 63.77%, respectively. Our findings demonstrate that the date fruits, date seeds and palm shell can be considered as good source of natural antioxidants.
