| The preliminary phytochemical screening of Euphorbia showei:f that the plant contained sterols, tannins, resins, flavonoid, sulphates, reducing sugars, saponin, carbohydrate and/or glycosides, chlorides and alkaloid. he paper chromatography investigation of free sugars showed that E. para lias contained arabinose, xylose, maltose, glucose and sucrose in the leaves and ste s at winter and summer,beside rafinose in the leaves at both seasons, fructose in the eaves and stems at winter and cellobisoe in the stems at both seasons.while it present in the leaves at summer only. Meanwhile, the chromatographic investigatioin of combined suga s revealed the presence of arabinose, rafinose, xylose, maltose, glucose in the leaves and stems at winter and summer, beside fructose in the leaves and stems at winter and cellobiose in the stems at both seasons, while it present in the leaves at surpmer only. The obtained Amino Acid Analyzer showed the presence of free amino acids; aspartic, therionine, serine, glutamic, proline, glycine. alanine, valine, isolucine, lucine, tyrosine. phenylalanine, histidine, ammonia and arginine in the leaves and stems at both seasons • beside lysine in the leaves and stems at summer. The data of protein amino acids hydrolysate revealed the presence of fifteen amino acid withldifferent of concentrations at both winter and summer. The total lipids and the fundamental chemical properties of lipidS of E. para/ias were detennlned. It was Obvious from the obtained G.L.C. res?lts that the unsaponified matter of leaves and stems at winter and summer contained 10 hydrocarbons, beside cholesterol, P,sitosterol and stigmaster91. G.L.C. chromatograms of the saponified matter revealed the presence of the salUrated falty acids caproic. caprylic, capric, lauric. myristic. palmitic, stearic and arachidic acid beside the unsaturated fatty acids, palmitoleic, oliee, linoleic, linolenic an~ eicosenoic acid in the leaves and stems at winter and summer. palmitoleic acid i the stems atsummer. While arachidic acid was defected in the leaves at summer and in stems at winter .beside erucic acid in the leaves at winter stems at summer as saturated. The results revealed marked qualitative and quantitative difference in t e chemical constituents of the leaves and stems of E para/ias at winter and summer seasons. | ||||
