DETERMINING THE PERCENTAGES OF PLANT EXTRACTS FROM THE LEAVES OF EACH OF OLIVES, PROSOPIS JULIFLORA, AND MIRABILIS JALAPA LINN(LALA ABBAS) USING DIFFERENT EXTRACTION METHODS AND PERFORMING FT-IR ANALYSIS OF THESE EXTRACTS

Abstract

Plant extracts are one of the important topics that researchers have been interested in in all periods, with their great importance and their entry into a variety of fields. The aim of this research is to identify the percentages of plant extracts obtained from the leaves of each of the olives, Prosopis juliflora and Mirabilis jalapa Linn (Lala Abbas), as the leaves of the plants were extracted by two different methods: extraction using the Soxhlet device and extraction by the maceration process. The results showed that the extraction method by Soxhlet device gave higher percentages than the maceration extraction method for plant extracts in all the samples used, and that the extraction yield of Prosopis juliflora leaves, which amounted to (15.58%) was higher than the rest of the extracts obtained in this research. The results showed that in terms of infrared spectra analysis, there is a high convergence of all the prepared extracts through the appearance of some effective functional groups such as (hydroxyl group OH, carbonyl group C-O and others).
