Gas chromatography-mass spectrometry (Gc-ms) analysis of ajwain (trachyspermum ammi) seed extract

Abstract

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%).
