dc.description.abstract Natural products especiallyfrom plants have different uses. In Sudan there are many plants that grow naturally they have many medicinal,traditional and other uses .The most common is plant of Hanzal(CitrullusColocynthis)grow in many desert areas.Theobjectives of this study isto detect the chemical constituents of Citrulluscolocynthisfruits and physicochemicalcharacterization of oil. Samples of Citrulluscolocynthisfruits were collected from Alkadro,Khartoum state.TheCitrullusColocynthis fruits were dried and crushed to separate the pulp, shell and seeds,The results ofchemical constituents of the CitrullusColocynthis fruits were studied, then the oil was extracted from seeds for physicochemical characterization and TLC analysis, Theextractionwas doneby solvent.The results of the study ofCitrullusColocynthis fruitswerecontaines of flavonoids, tannins, terpenoids, saponins, Cardiacglycosides and Alkaloids.The oil extracted from the seeds ofCitrullusColocynthis was 18%.The Physicochemical characterization showed that the density of the oil was 0.9136g/cm3, Refractive index was1.4751, Viscosity was 20 Pa , Colour Red0.9 and Yellow19, Iodine value was 5.75mg/100g of oil, Saponification value was 181.1 mg KOH/g of oil, Acid value was 3.26 mg KOH/g of oil, Free fatty acids was 1.63 mg KOH/g of oil , Peroxide value was 2.100 mg/100g of oil and Ester value was 179.47 mg KOH/g of oil, Unsaponifiable 0.02%, TLC results showed that CitrullusColocynthis oil similar citrulluslanatus and citrullussativus, and also contains oleic and linoleic acid but did not contain stearic acids.Future chemical characterization of the plant by Gas chromatography is required. . en_US
