fourier transform infrared spectroscopic analysis of kelussia odoratissima mozaff. (keluss) and portulaca oleracea: two valuable herbs

Introduction: kelussia odoratissima mozaff. (keluss) and purslanes with the scientific name portulaca oleracea have many uses in the food and pharmaceutical industries due to their antioxidant properties. the purpose of this study was to identify the functional groups of keluss and purslanes native to ilam by fourier-transform infrared spectroscopy (ftir) procedure. methods: dried seed powder of the plants was used. determination of functional groups of medicinal plants keluss and purslanes was done by the ftir method. the functional groups were identified and reported based on the obtained different spectra. results: based on the results of spectrometry, it was found that k. odoratissima has 9 spectra including n-h, c-h, c-h, c=o, c=n, c-h, c-n, s=o, and c-br. furthermore, it was observed that p. oleracea has 13 spectra including o-h, o-h, n-h, c=o, c=n, c=c, c-h, s=o, c-h, c-h, c-o, c=c, and c-h groups. conclusion: the results of the present investigation revealed that k. odoratissima and p. oleracea had a variety of ftir spectrum profiles including different functional groups that are responsible for their biological properties.
