This study aims to prepare nanoparticles from Curcuma longa L and Cosmos caudatus extracts, and to investigate their physico-chemical characterizations. The first step in this research was maceration extraction of Curcuma longa L and C. caudatus, using ethanol (96%), and formulated into nanoparticles. Nanoparticles were characterized using spectrophotometry UV-Vis, FTIR spectrometry, and SEM (scanning electron microscopy). UV-Vis spectra confirmed that formation of nanoparticles emerged in the UV-vis region around 420 nm. FTIR analysis revealed the existence of functional flavonoids compounds from the extracts, showing at wavenumber 1440-1420 cm-1. From SEM analysis, the formation of nanoparticles results in mostly flake-like morphology with particles size found within the range of 15-30 nm. The biologically synthesized nanoparticles could be of immense use in medical field for their potential as anti-cancer drugs. © Published under licence by IOP Publishing Ltd.
