摘要：

Fifty three phytochemical compound in the methanolic extract were identified of Cyperus iria L. The identification is based on the molecular weight, peak area, MS Fragmentation and, retention time,.GC-MS analysis of Cyperus iria L. found the presence of the compounds : (2S,3S)-2,3-Dihydroxy-2-isopropylbutyric acid [(5R,6S)-6-hydroxy-1-azabicyclo[3.3.0]oct-3-en-4-yl]methyl : 1,2,4-Benzenetriol : 4-Mercaptophenol : 2-Pyrazoline,5-ethyl-1,4-dimethyl : 5-Hydroxymethylfurfural : 2-pyrazoline,5-ethyl-1,4-dimethyl : Dodecanoic acid methyl ester : Undecanoic acid, 10-methyl-methyl ester : α-Cadinene; [1s-(1a,4ab,8aa)]-1,2,4a,5,6,8a-Hexahydro-4,7-dimethyl-1-(1methylethyl)-naphthalene: Aromandendrene : β-Maaliene: Methyl tetradecanoate : Methyl isotetradecanoate (iso-14:0): Phthalic acid, isobutyl octadecyl ester : Di-sec-butylphthalate : Cis-9-Hexadecenoic acid : z-(13,14-Epoxy)tetradec-11-en-1-ol acetate : Hexadecenoic acid,z-11 : Hexadecanoic acid, methyl ester : Dibutyl phthalate : 1-Butyl 2-isobutyl phthalate; 2-Methylpropyl butyl phthalate; Butyl isobutyl phthalate: Octadecanoic acid : 1-Pentadecanecarboxylic acid n-Hexadecanoic acid : 9-Octadecenoic acid, methl ester, (E) : Methyl stearate : Oleic acid : Trans-2-Dodecen-1-ol,trifluoroacetate : rac-1-Monoolein : Eicosanoic acid, methyl ester : 4,4-Dimethylcholestan-3-one, (5.alpha.)-: Oxiraneundecanoic acid, 3-pentyl-methyl ester,trans : Benzyl butyl phthalate : Beta.-sitosterol : Gamma.-sitosterol : 3-cyclopentylpropionic acid, tridecyl ester : Copaiferic acid B : 4-Vinylcholestan-3-ol # : Bisabolol oxide II : 1-Bromo-11-iodoundecane : Decanoic acid, 9-oxo-,methylester : Flexol plasticizer DOP: Polycizer 162: Phthalic acid, di(2-propylpentyl)ester : Pentadecane,2-methyl- : Butyl 9-octadecenoate : N-Methyl-1-adamantaneacetamide : Diethylmalonic acid, pentyl 3-phenoxybenzyl ester : 9-Borabicyclo[3.3.1]nonane,9-[3-(dimethylamino)propyl] : Dodecanoic acid,1,2,3-propanetrly1 ester : Phen-1,2-diol,4-fluoro-5-aminoacetyl-dimethyl ether : Tetrahydrofuran-2-carboxylic acid,dibenzofuran-3-ylamide : Benzenamine,4-methoxy-N-(triphenylphosphoranylidene) : Cyclodododecanol,1-aminomethyl : Ergost-5-en-3-ol,(3.beta.)-campesterol : N-(2-Acetylcyclopentylidene)cycioh exylamine. The plant contain many bioactive phytochemical compounds that may be useful as Antioxidant, Anticancer, Antimicrobial Activity, anti –inflammatory, Nematicide, Antihistaminic, Antieczemic, Insectifuge and others.
