Fig: FTIR graph for pure iron oxide nanoparticles On comparing the FTIR analysis for all the following compounds, DMSO dissolved in Thymoquinone IONP showed promising results in terms of the purity and the quality of Thymoquinone present followed by the methanolic extract and hexane extract, aqueous extract IONP. Thymoquinone IONP showed the least number of functional groups which implies that the yield of thymoquinone was not efficient from these solvents.
