Comparative analysis of synthesized waltheria indica leaf and euphorbia maculata herb zinc nanoparticle

Title : Comparative analysis of synthesized waltheria indica leaf and euphorbia maculata herb zinc nanoparticle

Abstract:

Zinc nanoparticles of Euphorbia maculata and Waltheria indica were synthesized and analyzed for their optical properties using UV/Vis spectrophotometer (peak absorbance at 380nm) and Fourier Transmission Infra-red Spectrophotometer (3200 and 3295cm^-1signifies OH; 2098cm^-1 represent CH₂, 1636cm^-1 represent C=O while the stretch around 600cm^-1could be attributed to the vibrations of elongation and of deformation of vibratory ZnO). The surface morphology of the synthesized zinc nanoparticles (Zn-NPs) were also taken into consideration using Q250 Scanning Electron Microscope from FEI Eindhoven the Netherland (E. maculata Zn-NP has an average diameter size of 3.766 nm while W. indica Zn NP has an average diameter size of 11.87 nm). Furthermore; the antimicrobial activity of the synthesized nanoparticles were compared with the diluted crude extracts of E. maculata and W. indicaas well as zinc sulphate hepta-hydrate solution while commercially available antibiotics were used as control against five bacteria isolates namely Staphylococcus aureus, Escherichia coli, Proteus mirabilis, Klebsellia pneumoniae and Pseudomonas aeruginosa as well as two fungi isolates namely Aspergillus flavus and Aspergillus niger; thus exhibiting varying susceptibility range against each isolates.  Anticoagulant activities of the nanoparticles were compared with that of zinc sulphate solution and the respective crude extracts while EDTA was used as control with anticoagulation value ranging from 2 minutes to 240 minutes. Antioxidant activities of the nanoparticles, zinc sulphate solution and the respective crude plant extracts were compared with that of ascorbic acid.
