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.
