Abstract
This work aims to study the antioxidant activities and chemical constituents of four Saudi date palm varieties (Ajwa, Kodari, Anbarah and Suqaey). Results showed variation in chemical composition and antioxidant activates. Carbohydrates (71.5-77.3 g/100 g dry matter) and moisture contents were the predominant competent in all flesh date palms (80.44-82.82%). Anbarah reported the highest protein and ash contents (3.50% and 2.32%, respectively) between the four varieties, while fat contents were low in the four types. Total phenols and antioxidant activities were higher in Ajwa compared to the other varieties. IC

of Ajwa, Kodari, Anbarah and Suqaey was 24.5, 25.55, 28.51 and 26.41 mg/ml, respectively. The antioxidant activities can be contributed to dates highly phenolic contents, which improve the antioxidant activities that could be used in food formulations.
