The objectives of this research were to determine the chemical composition of the extract of Trachyspermum ammi L. seeds by using gas chromatography-mass spectrometry analysis (GC-MS). The GC-MS is a matchless method for the study and measuring quantity of organic volatile and semi-volatile compounds. Gas chromatography is employed to separates mixtures into individual components employing a temperature-controlled capillary column. Mass spectrometry is utilized to recognize a variety of components from their mass spectra. In the present study, volatile/ semi-volatile compounds present in Ajwain seed extract were analyzed. Ajwain seed extract is extracted by soxhlet extraction method and then analyzed by GC-MS. Total of nine compounds were found and quantified in this study. The major bioactive compounds in Ajwain seed extract are 3,5-dimethylanisole (83.19%), 6-octadecenoic acid, methyl ester, (Z)-, 7-octadecenoic acid, methyl ester (7.42%), and 2-cyclohexyl-2,5-cyclohexadiene-1,4-dione, 4-oxime (3.01%).
