The purpose of this study was to assess the antioxidant capacity of lemongrass, turmeric and palmarosa essential oils. Through the technique of steam distillation, the essential oil extract was derived from natural sources. Several investigations have shown that essential oils' antioxidant potential is derived from their constituent parts. Here, the antioxidant capacity of the essential oils were assessed using two assays: The Ferric reducing antioxidant power (FRAP) assay and the α, α-diphenyl-β-picrylhydrazyl (DPHH) radical scavenging assay. According to the current study's findings, these plants' essential oils and their individual components can be utilized as natural antioxidants. Compared to lemongrass oil, the essential oils from palmarosa and turmeric have a higher potential for antioxidants. By using FTIR spectroscopy, the materials were characterised in order to evaluate the vibrational groups that were present in them. Aspergillus Niger, Salmonella Typhi, and Escherichia coli were the microbes against which the antimicrobial activity of essential oils was tested.
