Gas Chromatography-Mass Spectrometry (GC-MS) Analysis of Some Plants Extract

Abstract

The Gas Chromatography-Mass Spectrometry (GC-MS) analysis of four plant extracts—Tamarindus indica Seed Extract (TISE), Tamarindus indica Pulp Extract (TIPE), Acacia nilotica Seed Extract (ANSE), and Acacia nilotica Pulp Extract (ANPE)—revealed the presence of diverse bioactive compounds with varying concentrations. TISE was found to contain seventeen bioactive molecules, with Dimethyl sulphide (42.68%), S-ethylmethanethiosulphonate (26.31%), and 9-octadecenamide (11.01%) as the predominant compounds. TIPE, with thirteen bioactive compounds, exhibited ethanethiol (74.29%) and 9-octadecenamide (11.55%) as the major constituents. ANSE comprised seventeen compounds, with Dimethylsulphide (13.85%), 2-Propanol (6.07%), 1,2,3-benzenetriol (5.22%), and 9,12-octadecadienoic acid (14.24%) being some of the most prominent. In ANPE, sixteen bioactive compounds were detected, with Benzoic acid, 3,4,5-trihydroxy, methyl ester (50.47%) and 9-octadecenamide (23.57%) dominating the extract.Dimethylsulphide showed the highest peak values in both TISE and TIPE, with retention times of 1.442 and 1.440 minutes and percent peak areas of 42.68% and 74.29%, respectively. In ANSE, 9,12-octadecadienoic acid exhibited the highest peak at a retention time of 52.916 minutes with a peak area of 14.24%. In ANPE, Benzoic acid, 3,4,5-trihydroxy, methyl ester had the highest peak, with a retention time of 41.107 minutes and a peak area of 50.47%. This study highlights the presence of several bioactive compounds, particularly fatty acids, amides, and aromatic molecules, which suggest potential applications in fields such as pharmaceuticals, nutrition, and material science. Further investigation is recommended to isolate, identify, and characterize these bioactive compounds for their potential industrial applications, including in the development of eco-friendly corrosion inhibitors and other biotechnological use
