    Phytochemical and GC-MS analysis of zingiber offinale was carried out in the laboratory and with the aid of SHIMAZU Japan Gas Chromatography 5890-11 with a fused GC column OV 101 coated with polymethyl silicon (0.25 mm x 50 m). The result obtained confirmed the presence of alkaloids, flavonoids, saponins, glycosides, tannins and phenols in the plant. Twelve peaks were obtained from the he spectra of the GC-MS. peak 1 corresponds to Furan-3-carboxaldehyde with m/z 128 and molecular formulae C6H8O2, peak 2 was identified as Benzene -1-(1,5-dimethyl-4-4hexenyl)-4-methyl m/z 202 with molecular formulae C15H22. Peak 3 as ,1-,3-cyclohexadiene-5- (,5 diethyl-4-hexenyl -2-methyl (zingiberene) m/z 204 with molecular formulae C15H24, peak 4 as Alpha farnesene m/z 204 with molecular formulae C15H24. Peaks 5,6,7,8,9,10,1,12 occurred at m/z; 220,204, 194,242,,256,296,282, 296 corresponding to butylated hydrotoulene, C15H24,,cyclohexene-3- (1,5-dimethyl-4-hexenyl-6- methelene C15H24, 2-butanone-4-(4-hydroxy-3-methoxyphenyl C11H14O3, methyl tetra decanoate C15H32O2, n-hexadecanoic acid C16H32O2, 9-octadecenoic acid methyl ester C09H26O2, Octadec-9-enoic acid, C18H34O2, Gingerol C17H28O4 and Ricinoeic acid C18H24O2 respectively
