Introduction: Date palm (Phoenix dactylifera) has been used for nutritional and medicinal purposes. They are used as medicine for the treatment of several diseases and also highly recommended for pregnant women before and after delivery. Objective: The present work aims to explore the phytochemicals present in unripened Dates (RD) and Yellow Dates (YD)and assess their antioxidant property. Methods: Different solvents such as aqueous, methanol, benzene, petroleum ether and chloroform were used to extract the phytochemicals present in it DPPH (2, 2-diphenyl-1-picryl-hydrazyl-hydrate), FRAP (ferric reducing antioxidant power), Chela-tion of Fe2+ and SOD (superoxide dismutase) were used to assess the antioxidant activity. Results: The screening of phytochemicals showed the presence of alkaloids, flavonoid, phenolic compounds, saponin, tannin, steroid and carbohydrate, however, the antioxidant activity revealed that the % inhibition of DPPH, FRAP, Chelation of Fe2+ and SODwere about 94.05 ± 2.73, 77.91 ± 2.96, 88.02 ± 2.50 and 82.50 ± 2.58 respectively for RD and 85.13 ± 2.74, 68.03 ± 2.66, 79.64 ± 4.0 and 72.30 ± 2.10 respectively for YD. Conclusion: Both YD and RD unripe date palm demonstrated high phytochemical content and are potent antioxidant activity. The analysis of qualitative and quantitative phytochemicals such as alkaloids, flavonoids, phenolic compounds, tannins, terpe-noids and steroids revealed that the antioxidant activity of the YD and RD is due to these phytochemicals. © IJCRR.
