Twenty and twenty five phytoconstituents compounds were distinguished in methanolic extract of roots and leaves Capparis spinosa L. respectively. GC-MS analysis in extract of root revealed the existence of Spiro[2.4] heptan-4-one; Oxacyclododecan-2-one Oxacyclododecan-2-one; D-glucose, 6-O-?-D-galactopyranosyl; Dimethyl fumarate; 2-Pyridineacetic acid, hexahydro; DL-Leucine, N-glycyl; 6-Acetyl-?-d-mannose; 4-Amino-1,5-pentandioic acid; 4H-Pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl; 2H-Benzotriazole, 2-methyl; Acetate, [3-(acetyloxy)-4,5-dihydro-5-isoxazolyl]methyl; ?-D-Glucopyranoside, O-?-D-glucopyranosyl-(1.fwdarw.3)-?; Thieno [2,3-d] pyrimidine-6-carboxylic acid, 5-methyl-4-oxo-3-;1H-Benzotriazole, 1-methyl-; Benzoic acid, 4-methyl, [4-(methoxycarbonyl)phenyl]methyl; 2,5-Octadecadiynoic acid, methyl ester; 2-(2-Azepan-1-yl-2-oxoethyl) -1-hydroxy-1-phenyl-octahydro; 9-Hexadecenoic acid; Propanoic acid, 2-(3-acetoxy-4,4,14-trimethylandrost-8-en-; 2,7-Diphenyl-1,6-dioxopyridazino[4,5:2 ,3 ]pyrrolo[4 ,5 —d]pyrico. GC-MS test in extract of leaves confirmed the existence of be3-Azabutyl-1-ol, 4-cyclopropyl-3,3-dimethyl-, bromide; Methyl 6-oxoheptanoate; 5-Oxohexanethioic acid, S-t-butyl ester; 1-Methyl-2-pyrrolidineethanol; DL-Leucine, N-glycyl-; 4-Hexenal, 6-hydroxy-4-methyl-, dimethyl acetal, acetate, (Z); Octanoic acid, 6-hydroxy-8-methoxy-, ?-lactone; Dithiocarbamate, S-methyl, N-(2-methyl-3-oxobutyl); 1-Methyl-pyrrolidine-2-carboxylic acid; Pyrrolizin-1,7-dione-6-carboxylic acid, methyl (ester); 2-Cyclohexylpiperidine; ?-L-Galactopyranose, 6-deoxy, cyclic 1,2,3,4-bis (methylboro); N-(1Hydroxy-4-oxo-1-phenylperhydroquinolizin-3-yl)carbamic; dl-1,6-Diaminoheptanedioic acid; Cholestan-3-ol , 2-methylene, (3?,5?)-; 3,6-Diazahomoadamantan-9-one Hydrazone; 17-Octadecynoic acid; n-Hexadecanoic acid; D-Streptamine, O-6-amino-6-deoxy-?-D-glucopyranosyl; 9,12,15-Octadecatrienoic acid, (Z,Z,Z)-; 5,8,11-Heptadecatriynoic acid, methyl ester; 18-Nonadecenoic acid; 3 ,8,8 -Trimethoxy-3-piperidyl-2,2 -binaphthalene-1,1 ,4,4 -tetr and (+)-?-Tocopherol, O-methyl. FTIR analysis implemented on five parts of capers and showed entity of variations when compared to the methanol extract of each part with the rest of the parts add to variation in original and methanolic extract for each parts in plant and manifested the appearance of alkenes, alkanes, esters, ethers and carboxylic acids
