Gas Chromatography Mass Spectrometry and Fourier transform Infrared Spectroscopy analysis of methanolic extract of Mimosa pudica L. leaves

Abstract

The present study investigates the chemical constituents of a traditionally used ethno-medicinal plant Mimosa pudica Linn using Gas Chromatography Mass Spectrometry (GC/MS) and Fourier Transform Infrared Spectroscopy (FTIR). The identification of phytochemical compounds was based on the peak area, retention time, molecular weight, molecular formula, MS fragment ions. Thirteen phytochemical compounds were identified in the methanolic extract of leaves Mimosa pudica. The GC-MS analysis provide the existence of N, N'-Bis (Carbobenzyloxy)-lysine methyl(ester, Acetamide, N-methyl-N-[4-[4-fluoro-1-hexahydropyridyl]-2-butynyl]-, o-Ethylhydroxylamine, Propanamide, 2-hydroxy-, 1-Allyl-4-(4-methoxyphenyl)-1H-pyrimidin-2-thion, Gentamicin a, Mannosamine, 1H-Indole, 4-(3-methyl-2-butenyl)-. The FT-IR analysis revealed the presence of carbonyl (C=O) at 1705.3 Cm-1 , aliphatic stretching (C-H) at 2978.8 Cm-1 and 2944 Cm-1 and hydroxyl functional group (O-H) at 3313.6 Cm-1 These chemical compounds may exhibit various therapeutic properties such as antifungal, antibacterial, anti- inflammatory, anti-oxidant and others.
