الملخص

This study was conducted with the aim to extract and analyze the fruitspowder of Hyphaene thebaica, which brought from forest on the north ofAtbara River, in the Nile River State, Sudan. Two methods of extractionsfrom the fruits powder of H. thebaica were performed; extraction bymaceration using three different solvents including methanol , ethyl acetateand n-hexane, their yields were 21.67%, 0.66% and 0.64%, respectively.These extracts were subjected to phytochemical analysis which showed thepresence of saturated and unsaturated sterols, saponins, coumarins,carbohydrates, tannins, flavonoids and alkaloids .Yield of successiveextractions were methanol (26.77%) , n-hexane (0.62l%) and ethyl acetate(0.388%).GC-MS was used for quality and quantity evaluation of the hexane extractrevealed the presence of twenty compounds saturated fatty acids (38.66%)including palmitic acid (3l.48%), Hydrofol acid (2.57%) , unsaturated fattyacids (27.22%) including oleic acid (7.74%%) Linoleic acid (2.97%), andPalmitoleic acid (0.91%). The essential oil obtained from n-hexane extract ofseeds of H. thebaica revealed a total of twenty five compounds. The majorcompounds were saturated fatty acids (69.32%) including lauric acid(28.68%), myristic acid (l5.53%) and unsaturated fatty acids (30.00%)including oleic acid (24.67%) and linoleic acid (4.75%).Antioxidant activity was evaluated for all extracts. The results showed thatthe methanol extract (sox) possessed the highest activity with (70.5%) at theconcentration of 0.lmg/ml using DPPH assay. The most active extract wassubjected to TLC and visualized with vanillin-HZSO4 reagent. Sevencompounds were isolated by TLC, analyzed by Infra-red and UV. Visiblespectroscopy.iv
