Cymbopogon commutatus has been used as an ingredient in the manufacturing of soap and mosquito repellent. Herein, the chemical profiling of the C. commutatus aerial parts essential oil (CCEO) was constructed on the basis of the multiplex of GC-MS and nuclear magnetic resonance (NMR). Four nanoformulations-EO nanoemulsions (CCEO@NE), chitosan-coated (CSNPs@NE), silver nanoparticle-loaded (AgNPs@NE), and iron oxide-loaded (Fe
