Abstract
In this study, the Copper nanoparticles were green synthesized by using ethanol extract of Cordia myxa L. leaves as an antibacterial agent. The reduction of copper sulfate to copper nanoparticles was characterized by UV-visible and FTIR spectrophotometer. The results showed that UV-vis spectra showed peak at 400 nm. The antibacterial efficiency for different extracts: (A) Plant extract; (B) (Cu NPs), (C) (Plant extract with DMSO, DI Methyl Silvocside); (D) (Cu NPs with DMSO); (E) (DMSO) against different species of bacteria: Bacillus sp., staphylococcus aureus, pseudomonas sp. and klebsiella sp. were determined by measuring the diameter of inhibition zone using the disc diffusion method. The results showed that extract nanoparticles for both pseudomonas and klebsiella bacterium were recorded a high diameter of inhibition zone for both pseudomonas and klebsiella bacterium (19.3, 17.6 mm) respectively, while there was not inhibition zone with the Bacillus bacteria was not inhibition zone for all the extracts of Cordia myxa L.
